Message from the PresidentKen Martin, President of Diversified Technology, Inc.

At Diversified Technology, Inc. we have always strived to provide a quality product that not only fills the current needs of our customers

but also those of their future advancements. This requires forward thinking about the challenges that DTI will face, as well as the

end-customer's program. Trying to predict what market changes various industries will face while ensuring your current deliverables are

completed on time, proves oftentimes to be a complicated task.

Some of the future changes DTI is focusing on are covered in this issue of our custom publication. Two of the articles cover

AdvancedTCA and the transitional challenges facing the move from 1G and 10G to 40G. As with most things, our product line only

dictates a very minor part of the global changes that are needed to make 40G implementations both practical and functional in Telecom

and other industries. How these challenges are addressed shows the level at which DTI strives to understand and implement the needs

of its customers into a design, and demonstrates that we don't just pass on hardware built to spec to them. We actually put many hours

of consideration into developing a real solution for their application—not just hardware and software.

A second development mentioned is within our On-Board Vehicle Power (OBVP) program. The 10kW system is currently being

modified through EMI (electromagnetic interference) testing as well as having numerous hardware and software changes to allow

increased output of 30kW mobile power to our soldiers. Being an embedded computer provider, DTI knows first-hand that with increased

processing and computing performance comes the need for even more raw power. That's why we had a plan in place from day one to

move this product line on to 30kW and beyond.

I also want to point out a new product line that is growing at a rapid pace for us at Diversified Technology: our Gale Series of Wind Power

Inverters. These inverters were developed for a single customer through the knowledge we acquired dealing with the OBVP

inverters, and our efforts have since grown to multiple customers throughout numerous countries. The first unit is a 12kW inverter that

performs in a NEMA 1 enclosure. The second is a smaller 6kW inverter that performs in a NEMA 3R enclosure, and is designed to

handle a smaller class of wind turbines. Both of these systems are firsts for us in the growing wind power and alternative energy

market. We are having great successes and, through these successes we are learning many things that we feel could enhance our

product line even further. Through customer feedback on these products and market studies, DTI is now in development of a third

system that will offer more functionality and features than our current generation of inverters.

All of our embedded computing products and power inverters can be enclosed in chassis that are designed and manufactured in-house.

DTI is constantly updating our systems approach to provide our customers with not only subcomponents, but with a fully integrated

solution that gets them ahead of their competition.

Throughout its 39 year existence, Diversified Technology, Inc. has designed everything from industrial control boards, Ethernet switches,

hex-core processing blades, and integrated suitcase laptops to ruggedized mobile power systems, UHF and VHF antennas, and now

wind inverters. As a company we aim to use all of these engineering experiences in serving our customers and to truly offer them

diversified product solutions.

Providing a Cohesive Approach to Embedded Computing and Power Solutions

The Ethernet technology family has grown and evolved

significantly over its 35 year history. Every few years a set of

changes comes along that revolutionizes the way Ethernet

networks are used. Bandwidth increases are the most noticeable

changes, but they are not always the most important. Even with

40G (and 100G) Ethernet at our door step, there are other

important changes coming to Ethernet in next generation

devices. For the first time a group of new technologies can be

combined to make Ethernet lossless, which greatly extends the

number of applications suitable for Ethernet.

Layer 2 Ethernet networks are best-effort networks and can lose

frames for 3 main reasons: They can lose frames due to clock

differences between two devices, they can loose frames due to

a topology changes in the network, and finally, they can lose

frames due to congestion in the network. All of these reasons for

dropped frames need to be addressed in order for Ethernet to be

lossless. Luckily for us, all of these problems have been solved

with the technologies outlined below.

Timing

Ethernet devices are required to have local clocks with an

accuracy of 100 parts per million or better. That means two

perfectly compliant line-rate, wire-seed 1G Ethernet devices can

drop up to 298 frames a second due to clock differences between

them. In order to assure no frames are dropped due to clock

tolerance differences the end points need a synchronized clock.

There are two new technologies that address clock synchro-

nization in Ethernet networks. IEEE-1588v2 is a protocol layer

technology with support for frequency and time of day

synchronization and sub-microsecond accuracy. Synchronous

Ethernet (SyncE) is a physical layer frequency synchronization

technology with 10 parts per trillion accuracy. By using IEEE-

1588v2 or SyncE to synchronize the clocks between the end

points, lossless delivery of frames can be assured. In

AdvancedTCA it may even be possible for certain applications

to replace the synchronization clock interface with IEEE-1588v2

or SyncE.

Rbridges

Today’s L2 Ethernet networks use Spanning Tree Protocol (STP)

for loop prevention. STP blocks links that create loops, and it

takes several seconds to recover from topology changes.

Rbridges address these shortcomings of STP.

Rbridges are Routing bridges. Rbridges bring some routing

functionality to bridges (switches), as the name suggests.

Rbridges use the IETF TRILL (Transparent Interconnect of Lots

of Links) protocol to discover the network topology and provide

optimal pair-wise forwarding paths. The most radical change

rbridges bring to L2 networks is multipathing. A TRILL network

is not limited to a single tree like an STP network. TRILL

supports any arbitrary network - from a simple tree to a

complex mesh and all links in the network can be active. For

AdvancedTCA networks and high availability networks in

general, rbridges allow for much better utilization of resources

because all redundant links can be active at the same time.

Rbridges with TRILL have several advantages over traditional

switches with STP, including instant recovery from topology

changes, shorter paths, greater bandwidth, and lower latency.

Data Center Bridging

Network congestion is an issue in all data networks that needs

to be addressed. Today’s networks rely on device level QoS to

police and shape network flows by dropping frames to reduce

congestion. This solution is limited because the devices work

alone rather than in a group where they could be sharing

information. Data Center Bridging (DCB) is a network level

technology that allows network devices to work together to

mitigate congestion.

DCB is made up of 3 new protocols that work together to

control congestion (and a 4th protocol that encapsulates the

information from the other three). First, there is IEEE 802.1Qbb

Priority-Base Flow Control (PFC). Ethernet flow control has

been around for some time in the form of IEEE 802.3x. 802.3x

flow control is too heavy handed, and it’s all or nothing approach

often causes more problems than it fixes in most networks. PFC

extends 802.3x such that pauses can be issued per class of

service. This allows network devices to pause only lower

priority classes when there is congestion. The second and third

protocols work closely together. IEEE 802.1Qau Congestion

Notification (QCN) allows network devices to communicate

congestion status throughout the network. IEEE 802.1Qaz

Enhanced Transmission Selection (ETS) allows network devices

to communicate and synchronize bandwidth allocations to

traffic classes. Taken together the DCB suite provides a more

intelligent way of dealing with congestion that is both priority

and network aware.

Lossless Ethernet

Lossless Ethernet is a goal that the Ethernet community has been

working towards for a number of years, and with IEEE-1588v2

or SyncE, TRILL, and DCB, Lossless Ethernet is a reality. It

provides guaranteed frame delivery and guaranteed performance

levels. It can replace more expensive lossless fabrics and even

external clock networks while still remaining cheap. It provides

better support for virtual machine migration and allows the LAN

and SAN to converge onto a single network. Lossless Ethernet

is a major update to the Ethernet suite you will need to have in

your next generation network.

Today’s data center environments demand performance and

reliability at much greater levels than even 5 years ago. Uptime

for application and network resources reaching 99.999%

availability is becoming a more common requirement and not

just the rare case.

Application and web server redundancy can be achieved by the

use of high performance load balancers, server clustering and

virtual host control applications. Resiliency in the network is

provided by routing protocols such as OSPF and BGP for

routing at layer 3 in conjunction with non-stop forwarding and

redundant hardware features. Protocols such as VRRP provide

for host IP gateway redundancy.

Layer 2 Network Redundancy

In the past, multiple paths within the VLAN or broadcast

domains were also needed in the case of link or device failures.

With multiple paths to the same points in these networks, loops

are formed which left unchecked create broadcast storms that

can bring networks to a standstill. The spanning-tree protocol

(IEEE 802.1D) is implemented in layer 2 networks to automat-

ically block these loops so only one path exists eliminating loops

in the topology. As a result of link failures, spanning-tree will

un-block previously blocked ports to provide for path

redundancy. These operations can take as long as 30 seconds

and can impact traffic in other parts of the network and not just

local to the device on which the failure occurred. Diagram 1 is

a standard network topology used with spanning-tree (SPT)

providing loop prevention in a multi-access layer 2 network.

The diagram displays what happens when the uplink between

switch A and C fails causing SPT to re-converge and determine

the new topology. The link between C and D will still be in the

blocking state until SPT can determine the new loop-free

topology and start accepting data packets through the D

interface. This process can take up to 30 seconds during which

connectivity between the hosts and the IP default gateway will

be lost.

With just one connection to the host, path redundancy can only

be achieved by installing the link between switch C & D. More

than one physical connection can be configured to the host but

traditionally host IP stacks had no way of automatically

changing which NIC owned an IP address during failures. In

this case, a host with two different NIC connections to two

different access switches could still not achieve redundancy as

access to the primary IP address would be lost when failing over

to the second NIC. New host protocols have been developed

that give servers the ability to move IP address ownership

between NIC’s in the event of pre-defined failure conditions.

Two of these are IPMP (IP Multipath) in Solaris and NIC

Bonding in Linux. We will use IPMP as a reference for this

article.

A dvanced TCA

R

IPMP Operation Example

IPMP can be configured to monitor failures in 3 different ways. To monitor remote path failures, the IP gateway can be pinged at

specified intervals or ARP requests for the IP gateway can also be sent. The link state of the host NIC itself can also be monitored. In

the event of a failure condition, IPMP will move the owner of the IP address to the secondary NIC card and generate a gratuitous ARP

request from that NIC to enable MAC address learning on the new path to the IP gateway. When using IPMP, the redundant link between

switch C and D can now be removed eliminating the spanning-tree blocked port from the topology.

Page 10: DTI Custom Publication, 2010

Page 11DTI Wired : Get Connected with Diversified Technology, Inc.

While the failover times have been reduced there are still

disadvantages to using IPMP’s ping to monitor upstream path

integrity. As the number of hosts behind the access switches

grow, ICMP traffic to the gateway IP will become quite large.

Some layer 3 devices will de-prioritize ICMP traffic destined to

the device itself (L3 gateway IP) and responses to the hosts may

be dropped during times of heavy load. IPMP monitoring of the

host NIC link state will produce fast failovers (normally less

than a second), but they do not check the upstream path to the IP

gateway.

DTI’s Layer 2 Failover Feature (L2FO)

Diversified Technology, Inc. has developed a new feature for

both of our ATS1160 and ATS1936 switches that takes

advantage of the IPMP or NIC Bonding behaviors to provide

fast failover times while monitoring the upstream path to the

next hop switch. This is accomplished by the use of line

protocol monitoring (referred to as a “track” on the DTI switch)

of a specified interface and tying this monitor to the link state of

the switch host port or ports. If the line protocol of the tracked

link goes down, the track status will also change to down. Any

host interface that is tied to this track (CLI configurable) will

also have its’ line protocol status forced down. The host IPMP

NIC monitor on this link will force the failover to the secondary

NIC connected to a separate switch creating a new path to the

primary host IP address. Below is an example using only one

host and one uplink port similar to the previous example of

IPMP ping monitoring failover.

The big difference between using the ICMP monitoring feature

of IPMP and L2FO is time to failover (TTF). While the default

setting for IPMP path failure detection is 10 seconds which

translates to missing 5 ICMP replies from the IP gateway, L2FO

TTF is less than 500 milliseconds from tracked interface failure.

This TTF only takes into account the time between tracked link

failure and when the host port is shutdown. IPMP can be tuned

to failover in as low as 100 milliseconds but this creates an

overly large amount of ICMP traffic even from just one host and

would be impractical to implement in a production scenario. A

more reasonable setting for IPMP would be a 5 second failure

detection time but this is still much slower than using the L2FO.

Providing a Cohesive Approach to Embedded Computing and Power Solutions

Page 11: DTI Custom Publication, 2010

Page 12DTI Wired : Get Connected with Diversified Technology, Inc.

Another important feature of L2FO is the ability to track the state

of port-channels (or Link Aggregation Group - LAG) as well as

individual interfaces. The number of links currently active in

the LAG as well as the line-protocol state can be monitored and

used to trigger failover. The “minimum links” feature simply

put sets the required number of interfaces that need to be active

in the LAG for the track to be considered in the up state.

Primary L2FO Features

• Up to 254 individual tracks

• Multiple failover tracks per host port interface

• Track port-channel interfaces

• Track number of active interfaces within a port-channel

• Track route prefixes in the route table

• Can be used on any interface type

(Fiber or Copper Gigabit or 10 Gigabit)

• Failover times less the 500ms

(from tracked link failure to failover action)

• Available on the ATS1936 and ATS1160 from

Diversified Technology, Inc.

• Works independently of the connected host protocol

This new Layer 2 Failover feature provides networks with the

ability to rapidly replace failed links – far faster than ICMP

monitoring via IPMP and NIC Bonding in Linux and its far

easier to configure as well. As we discussed in this article, while

using IPMP can suffice for some networks, too low of a TTF

setting results in an overabundance of ICMP traffic, and

reasonable settings are far slower than utilizing switches

designed with this L2FO feature.

CompactPCI has come a long way since it was first introduced

15 years ago. DTI’s first two CPU boards designed around this

form factor were based on Intel’s Pentium and Pentium PRO

processors with a maximum speed of 233MHz. Oddly enough

we still get support calls from time to time on these 2 products.

This illustrates the longevity of CompactPCI as well as the

quality of design the specification has provided for so many

years.

The PICMG 2.0 Specification, CompactPCI, was developed in

1995 by PICMG, which is a consortium of companies who

collaboratively develop open specifications for high perform-

ance, leading edge products utilized in embedded computing

industries. PICMG 2.0 is electrically a superset of desktop PCI

with a different physical form factor. CompactPCI utilizes the

Eurocard blade form factor popularized by the VME bus.

Defined for both 3U (100mm by 160 mm) and 6U (160mm by

233 mm) card sizes, CompactPCI has grown in to a major

computing form factor in numerous markets including areas it

wasn’t originally intended for, such as military applications.

Over the years, DTI has designed approximately 50 products

based on CompactPCI specifications. This list includes CPU

boards, Switches, RTM Modules, Mezzanine cards for added

performance, and fully integrated chassis with support for up to

18 slots for CPU Boards. The orientation of the boards design

provides good cooling through the chassis and allows it to

handle shock and vibration levels beyond the normal slot card

and motherboard systems.

CompactPCI uses inexpensive fabrics, such as 1G Ethernet, to

create an interconnect environment through the backplane of the

chassis. As newer standards like 10G and 40G come to market,

more and more users of CompactPCI look to move towards

AdvancedTCA and other form factors that are designed to

support those higher technologies. However, CompactPCI still

provides a fit for many applications whose vendors utilize the

low cost platform along with processor upgrades to continue

their programs well in to the future.

and how they communicate to each other via the Ethernet bus.

Emerging Markets

DTI has noticed a decided uptick in Military/Aerospace

CompactPCI deployments over the past 5 years. For some

applications, VME is long in the tooth and OpenVPX is not

market ready. Plus these, along with AdvancedTCA, can be

much more expensive technologies than CompactPCI. Many

military applications simply need a proven COTS technology

that can perform, not the cutting edge.

Within CompactPCI there is an increasing need for powerful

switching technologies as PICMG 2.16 deployments continue.

For those of you that are unfamiliar with 2.16, it employs a

packet-switching backplane for the system. This extends the

CompactPCI family of products to overlaying based switching

architectures on top of the existing CompactPCI. This will

extend communication and data throughput capabilities for the

network. This means L2/L3, CoS/QoS, and other network

management features are now available over the 1GbE network

within the CompactPCI platform.

A few of the growing CompactPCI Markets that we see are:

1. Avionics and Flight

• Includes Naval based Control Systems

• In-flight Entertainment (Video, Messaging, Internet, etc)

2. Medical

• Records Systems, Real-Time Imaging, Patient Care Systems

3. Military

• Fairly easy to “harden” or ruggedize for military

• Submarines, Ships, Air, Ground vehicles

Advancements to CompactPCI

PICMG recently announced the adoption of the PICMG 2.30

specification, called CompactPCI® PlusIO. The specification

will add PCI Express, Ethernet, SATA, SAS and USB

extensions to the CompactPCI family of specifications while

preserving the existing PCI bus connectivity. The 2.30 spec

defines the use of previously reserved rear I/O pins for the

32-bit CompactPCI system slot with new high-speed

serial signals while still maintaining interoperability with

existing CompactPCI standards.

CompactPCI Serial, PICMG 2.31, will be a new industrial

standard from PICMG for modular computer systems.

CompactPCI Serial uses only serial point-to-point connections

and its mechanical concept is based on the proven standards of

IEEE. CompactPCI Serial includes different connectors that

permit very high data rates throughput but lacks some

backwards compatibility. The standard adds USB and SATA

connections while requiring no bridges, switch fabrics or

custom backplanes. There is a dedicated PCIe lane for high

speed needs.

Conclusion

The CompactPCI Marketplace is still growing in places such as

medical, military command centers and avionics. It provides

many COTS features that make it ideal for most any applica-

tions due to the design and robust switch management features

which are needed for network deployments. DTI’s commitment

to this standard and its future additions and upgrades will help

to continue the growth of the CompactPCI market.

The Gale Series of Inverters

Diversified Technology, Inc.’s Gale Series of wind turbine inverters are variable power,

high frequency power inverters developed specifically to serve the wind power market.

When combined with a tower-mount wind turbine, Gale Series inverters take the

variable electric power generated and create manageable, smooth current that can

be sold to the utility.

Managed by DTI's Green Power Technology, the Gale Series inverters allow a

wide input voltage range with energy-saving low speed power mode to allow

for smooth operation at minimal turbine revolutions, and other features

designed to meet specific needs of the wind power

market. DTI’s Soft Grid Technology allows

the inverter to produce power during

wind gusts that would otherwise cause over voltage on the grid. This is

useful in rural locations during light local loading conditions. This maximizes

profits for the operator while preventing annoying system resets.

Harnessing the power of wind was a major factor in the

evolution of human civilization. From sailing to milling, wind

has played a vital role in human lives, and has helped shape the

world throughout history. Today the impact of wind power on

our daily lives has dwindled, as industrialization and the

increasing use of fossil fuels has moved wind power generation

to the margin of energy production methods. However, as non

renewable energy sources deplete and the search for renewable,

maintainable, and efficient energy sources increase, the use of

wind is undergoing a rebirth as an important energy source for

humanity.

Power generation with wind occurs via the conversion of wind

energy into a useful form, such as using wind turbines to

generate electricity. The first modern wind turbines were small

compared to today’s wind turbines, with maximum output power

reaching only 20 to 30kW. Since then, wind turbines have

increased greatly in size and power output, with some units now

capable of 7MW of output. Energy production from wind has

expanded in use to many countries throughout the world.

The amount of world energy produced by wind has been

spiking recently and doubled in the past three years. Many

governments have pushed for increased renewable energy

production and usage of wind power, which has helped several

countries achieve relatively high levels of wind energy

generation. Countries at the forefront of wind energy utilization

include Denmark, Spain, Portugal, Germany, the Republic of

Ireland, and the USA. As of May 2009, eighty countries around

the world were using wind power on a commercial basis.

Wind Farms

Wind Farms are groups of turbines that are interconnected via a

power collection system and communications network used in

aggregate to generate power. Wind farms may be located in

open farmland or on off-shore platforms that take advantage of

coastal winds.

Large scale wind farms may be directly connected to the power

grid in order to supplement traditional energy production forms.

Smaller turbine applications are typically used to provide

electricity to isolated or remote locations or to provide power

generation for a small facility. Electric utility companies will

“buy back” energy surpluses produced by smaller domestic

turbines, which is a process known as “Net Metering.” The

value of the energy surplus produced by a small-scale, grid-tied

turbine is credited to the turbine’s owner. Net metering and the

clean, renewable, and sustainable aspects of wind make it an

attractive primary or secondary energy source for many

applications.

The amount of energy generated by a wind turbine is a function

of the frequency and speed of wind a given location receives

over time. A consequence is that wind energy is variable and is

often generated in short bursts – thus wind is an inconsistent

mechanism for energy production when compared to other

power generation methods. Technologies such as shaping and

smoothing, grid energy or battery storage methods, and energy

demand management are used to address the variability and

inconsistencies related to wind power generation.

Big Wind versus Small Wind

The overall wind turbine market can be divided in to 3 classes:

1. Small Wind TurbinesThese turbines have power ratings of 100kW and below

and are generally for residential and small businesses.

2. Community Wind TurbinesThese turbines have power ratings between

200kW and 1MW.

3. Large Wind TurbinesThese turbines have power ratings above 1MW.

DTI’s Focus on the Small Wind Turbine Market

Small Wind Turbines are turbines whose production capability

is roughly 100kW or less. Typically used to power homes,

businesses, farms, and other single-site units, these turbines may

be set up as stand-alone systems or interconnected to the grid.

The Small Wind Market has drastically increased growth, in part

due to lower installation costs. There were an estimated 19,000

Small Wind turbines installed during 2009, amounting to a 78%

increase in total kW power output and adding 17.3MW of

installed energy capacity. The total Small Wind capacity for the

United States is estimated to be 80MW.

Some wind turbine manufacturers design their turbines with an

induction generator rather than a power inverter. Their main

reason for doing so is that power inverters add technical

complexity and cost while induction generators allow for an

easier, cheaper method to interconnect with the utility grid. This,

however, is generally not the best method, because the

induction generator does not contain key attributes that an

inverter provides, such as higher quality output power and

usability with a wider range of wind velocities.

Inverters Serving the Wind Power Market

Diversified Technology, Inc.’s Gale Series of wind turbine in-

verters are variable power, high frequency power inverters de-

veloped specifically to serve the wind power market. Combined

with a tower-mount wind turbine, the inverter takes the variable

electric power generated and creates a manageable, smooth cur-

rent that can be sold directly to the utility.

The Gale Series is managed by DTI's Green Power Technology,

which allows the inverters to accept a wide input voltage range

with energy-saving low speed power mode that in turn provides

for smooth operation even at minimal turbine revolutions.

DTI provides Soft Grid Technology which allows the inverter

to continue to operate even during wind gusts that would

otherwise cause over voltage on the grid. Soft Grid Technology

dynamically lowers to the output power if the grid voltage

approaches the over-voltage fault limit. This is useful in rural

locations during light local loading conditions. This technology

allows the operator to maximize profits while also preventing

those annoying system resets.

Many wind inverters on the market are simply modified solar

inverters. These units are very similar in construction and

features regardless of their application, so inverter manufactur-

ers slightly modified their designs so that they would fit for a

wind turbine application. The Gale Series of wind inverters was

designed from the start for wind applications. This includes built

in rectification for the AC input, so no external rectifier box is

needed.

DTI designed its Gale Series to comply with standards set for

grid-tied operation, safety and electromagnetic compatibility

including: UL 1741 and CSA C22.2 No. 107.1-01. The Gale

series also accepts a wide range of input voltages from 85 to

400VAC. Once the 85VAC input is reached and the inverter

initializes, the input voltage can then drop to 50VAC input

before the inverter can no longer produce power. This allows the

inverter to produce power even during light wind velocities.

NEMA 1 (12kW) and NEMA 3R (6kW) enclosures provide

operation in controlled elements that protect the internal

components of the inverter. The inverter also includes built-in

disconnect for utility grid interaction which is isolates the

inverter from the grid during any faults. The unit also has built-

in thermal sensing, and will reduce output power or shutdown

automatically if temperatures exceed safe operating conditions.

The Future of the Small Wind Turbine Market

Isolated residences and businesses situated in good wind

locations continue to purchase smaller turbine systems to reduce

or eliminate their dependence on grid electricity for economic

reasons. Wind turbines have been used over these many decades

in remote areas for household electricity generation in conjunc-

tion with battery storage and this is only going to increase as

turbines become cheaper with a lower cost to install and more

widespread availability.

In time, wind energy could be the most cost-effective source for

electrical power. In fact, there’s a good case to be made for

saying that it already has achieved this status. Major technology

developments enabling the use of wind power commercializa-

tion are being made daily. There will be infinite refinements and

improvements and one can make the assumption that the

eventual push to full commercialization and deployment of wind

technology is very near. Companies are taking advantage of

public interest, the political and economic climate, and

marketing factors to position wind energy for its next rounds of

deployment.

The military's demand for tactical power on the battlefield has

quadrupled in the past ten years and the best estimates are that

it will quadruple again this decade.

What is tactical power?

Tactical power refers to mobile power used on short term

military missions in support of a strategic objective. This

suggests a system that highly maneuverable and very rugged.

How much tactical power is needed?

That's like asking a computer engineer how much memory he

wants on his system. What ever you give him today, he'll want

twice that amount tomorrow. There are a myriad of uses for,

and numerous types of, AC power on the battlefield used in

support of the overall mission. For example, having access to

120 vac, 60 Hz in a remote location to power up communica-

tions, computers, and other specialized equipment is needed.

Mobile power must also be provided for the vast array of

computer and communication equipment assembled in a

Tactical Operating Center (TOC). Mobile power can also be

used to run advanced laser weapons.

The examples above will require different levels of power. The

general purpose application can typically be satisfied with a

10kW source, the TOC will likely require 30kW to 60kW,

depending on its configuration. Advanced laser weapons of the

future will require upwards of 100kW. As the power level

demands increase for the various applications, challenges to

meet those power levels with a rugged and highly portable AC

power source increase.

Yesterday, and to a large extent today, tactical power was and is

supplied by diesel generators. The down side of this is

logistics. The larger the AC load demand, then the larger the

generator required. The larger and heavier the generator, the

larger and heavier the required trailer becomes for towing them

around. The larger the trailer becomes, the less agile, or mobile,

the vehicle becomes that is towing the load.

Why can’t someone develop a means to provide AC power

by utilizing the vehicle's engine as the primary source?

That's exactly what the concept of On-Board Vehicle Power

(OBVP) addresses. However, the laws of physics apply and to

develop a 10kW OBVP system for installation on a vehicle, such

as a HMMWV with a 28 VDC alternator, that alternator must

put out 400 to 450 amps. The fact is that these alternators are

already in the Army's inventory today.

While the military has aggressive programs in place to move

toward Hybrid Electric HMMWV's there is a sizeable base of

existing vehicles that are candidates to be retrofitted with 10kW

On-Board Vehicle Power today. That brings us to applying

today's technology toward the application of a 10kW OBVP

system for retrofit into a portion of the more than 100,000

HMMWV's currently in use. Providing these vehicles with an

OBVP system that can supply continuous AC power eliminates

the need to trailer diesel generators. Consequently, the vehicle

can now negotiate terrain that it could not previously take on

while towing a trailer.

Up to 30kW of Mobile PowerOn-Board Vehicle Power (OBVP) Beyond 10 Kilowatts

Page 22: DTI Custom Publication, 2010

Page 23DTI Wired : Get Connected with Diversified Technology, Inc.

The different types of AC powered equipment used on various

missions, necessitates a variety of voltage levels and operating

frequencies of AC power. Due to the laws of physics mentioned

earlier, this provision is no simple task.

Regardless of whether the soldier needs single phase 120 vac or

3 phase 208 vac, and at 50Hz prevalent in Europe, or in a radar

installation where power at 400Hz is the frequency of choice,

the OBVP system must be able to provide all of the frequency

and voltage options. Additionally, Total Harmonic Distortion

(THD) is critically important to sophisticated communications,

computers and other specialty electronic systems. High THD

can render this type of equipment inoperable. Therefore low

THD is essential to completing the mission.

Previously, commanders have dealt with defined combat lines

and specific operational theaters and occupation directives. In

the modern theater this is no longer the case, and power

generators and techniques of the past cannot adequately power

the military and its systems of the future. While technology has

improved, certain characteristics of Tactical Quiet Generators

such as noise, lack of mobility, serviceability constraints, the

need for extra vehicles to carry fuel and generators, and other

logistical issues that are inherent to the design and use of these

Tactical Quiet Generators has created battlefield nightmares for

the operators, not to mention increased costs and swollen

budgets for commanders to accommodate these logistical

shortcomings. All of these issues are in direct opposition to the

current military desire to be “lighter, faster, stronger, and

smarter.” These logistical issues must be overcome to maintain

U.S. military dominance in active combat theaters.

To mitigate these shortcomings inherent in current power solu-

tions, there has been a drive to develop on-board vehicle power

systems. These power systems are compact, lightweight, and

provide the military with the mobility desired and the robust

power needed by the next generation of computer systems.

Advances in the inverter technology used in on-board vehicle

power systems, such as the increasing use of high power FET's

and IGBT's to design high powered inverters, have spurred key

developments in these modern power units. A simple conversion

from the 28VDC source to single phase, 120VAC/60Hz is not

enough. Systems must also be designed for mobility, servicea-

bility, environmental ruggedness and accommodate space con-

straints as well. To this end, OBVP units do not require an

external fuel source and can be mounted directly to the

HMMWV without decreasing needed cargo space. OBVP units

also provide a wide range of output power and frequency com-

binations to the end application.

OBVP Systems: Solving the Deployable Power Crisis

Modern OBVP units are designed for use in rugged environ-

ments and to be highly mobile. Taking power from the host

vehicle's 28VDC electrical system, output power levels can

range from 2kW to 10kW. To provide inverter system security,

the VPS10K system employs pre-charge circuitry to limit

current inrush, transient protection circuitry, feedback monitor-

ing, under voltage protection and over current protection. The

VPS10K can interface with alternate controllers allowing

flexibility of operation.

A throttle control, that is part of the OBVP system, monitors and

controls the speed of the engine and hence the alternator to

match the alternator's output to the load the inverter is powering.

(This is true in stationary mode only.) The vehicle throttle

control system monitors the condition of the load and the power

supplied by the inverter and communicates this to the operator

via an interface that shows the operator graphically the status of

the vehicle electrical system and of the inverter. The VPS10K

can additionally interface with alternate controllers allowing

flexibility of operation.

The Graphical User Interface (GUI) allows the operator to

quickly determine the frequency of the power the inverter is

delivering to the load. It also displays the charge condition of

the vehicle's batteries. The GUI allows the operator to turn the

entire system ON and OFF and also allows the operator to

enable and disable the inverter itself.

The OBVP inverter is mounted onto the HMMWV in a space

that does not affect the cargo capacity or function of the vehicle

and allows instant availability to power in any area to which the

HMMWV can maneuver. The modular design method of the

inverter's main components and the method of connecting the

peripheral components means that the OBVP system can easily

be removed from one HMMWV, returning the vehicle to its

original configuration, and quickly and readily installed on other

vehicle platforms as needed. This provides the ability to deliver

critical power to areas of the battlefield, under harsh environ-

mental conditions, ensuring that critical systems are operational

at all times.VPS10K

Page 24: DTI Custom Publication, 2010

The Challenges in Gaining 30kW of Mobile Power

As mentioned previously, the laws of physics apply and

generating 30 kilowatts of AC power from the engine and

electrical system of a HMMWV is not an easy task.

There are three main challenges to address in designinga 30kW On-Board Vehicle Power system:

1) The transfer of power from the prime mover, which is the

HMMWV's engine, to the alternator that develops the

voltage necessary for input to the inverter. All of the

mechanical losses must be taken into account, as well as

the needs of the vehicle itself and the power needed to be

supplied to the inverter. To this end, the design of the

system to transfer power from the engine to the alternator

is very rigorous. Various systems have been examined and

the most efficient method will be adapted.

2) +28VDC is not enough to generate 30kW of AC power.

A new alternator is needed that converts the engine's power

to a voltage high enough to allow the inverter to output

30kW of AC power. This new alternator has been

designed and tested and has shown that it is possible to

generated 30kW of power with an OBVP system as

opposed to pulling a heavy diesel behind the HMMWV.

3) The electronics necessary for such a high power level

generates a lot of heat. Clever packaging techniques must

be used to make the inverter fit in the allotted space and to

function well under all conditions. Cooling the electronics

cannot be accomplished with convection cooling due to

size and weight constraints. This task is possible with

liquid cooling and that creates it own set of challenges to

the OBVP system designer. Among them are primary heat

transfer, circulating the coolant and the critical heat

exchanger interface with the inverter's electronics.

Realizing Tactical Goals with OBVP Systems

As advances in battlefield technology force the requirements of

higher and more mobile power solutions, On-Board Vehicle

Power units will find their way into many deployments. The

military’s focus on faster, lighter, and stronger requires the use

of new technology to power the next the generation of computer

and communication systems. These systems and where they will

be deployed will all require new mobile, rugged, power

solutions. Trailer-towed and Skid-mounted power generators

fail in these regards, as they add bulk, reduce mobility, and

require external fuel (diesel) to operate, which further reduces

the cargo capability of a military vehicle. Mobile Vehicle Power

systems, like Diversified Technology’s VPS10K, that draw

power directly from the alternator and do not impede

much-needed cargo space will be the go-to solution for the

deployment of on-battlefield systems in the 21st century

military.

Dallas, where he serves teaching gospel studies, and in fundraisers for charity. Marcelo loves to

travel with his family, playing tennis, and sailing.

I like to joke that at times the position of CTO requires predicting the future, so let’s see how accurate I am at this.

The Economy

There will be no overnight turn around, but more of a slow gain akin to the long recovery seen in 1990s Japan. We have not

seen the price declines and deflation that Japan saw, but everything about this economy, from an Engineer’s view, looks as

though there is a similarity between now and Japan’s economic problems of the 1990s. I am naturally a technology bigot,

believing that it can heal everything. Technology developed for World War I helped the boom of the 1920s. I consider the boom

of the 1980s fueled by personal computers. We now need a technology shift to recover, and the best bet I have is switching to

a hydrogen/natural gas economy instead of an oil-dependent one, and technology would be needed to make that shift. Solar,

biomass and wind will help, but we need something revolutionary like the airplane. My dark horse pick for that technology

is Artificial Intelligence, but not your father’s AI. I am thinking of the AI of Jeff Hawkins' “On Intelligence.” I believe we will see a deployment of

that in the 1st half of this decade on a system that will be “taught” more than “programmed”.

AdvancedTCA

The jump from 10G to 40G Ethernet will likely see a 4x increase in AdvancedTCA usage. With nearly all of the interoperability problems solved,

AdvancedTCA will also become a “Best-In-Breed” shop for users. Those users need not choose stovepipe and vendor locked-in models from some

players. AdvancedTCA is already entrenched in Telecom and will not be replaced, but AdvancedTCA’s growth will come via the Military, and it will

see more success in that market than its original Telecom market – making it the Tang of the 2010s.

PICMG 2.30 and PICMG 1.3

CPU performance via many cores and multithreading is growing quickly. The PCI-Express bus is well supported in both current and future chipsets.

This will drive some users away from 1U/2U motherboard systems and back to systems with larger slot count chassis. Use of large slot count chassis

was a mainstay of the late 1990s, but much of that was lost to the 1U/2U systems of the world in the 2000s. Some will come back in the 2010s, and

this positions PICMG 2.30 and PICMG 1.3 very well.

Now that my predictions have been made, we just have to sit back and see how accurate I am.

When a program takes the single board, passive backplane

system in to the next decade and beyond, there are many

obstacles that must be faced. They range from components

going EOL to new software requirements that demand increased

hardware performance. PICMG 1.3, which is also known as

SHB Express, was created to offer PCI Express specifications

for the slot card computer. The demanding environments of

industrial automation, military, medical and telecom will require

full upgrades to PCI Express from PCI/ISA to compete in the

future.

What is the difference between PCI and PCI Express?

PCI and PCI Express are both types of peripheral card expansion

slots. PCI was created in 1993 by Intel and became the standard

in peripheral expansion. Network interface cards, video cards,

I/O expansion cards, and sound cards were all PCI-based. As the

amount of data pushed through the PCI bus increased, PCI-X

became popular in servers. PCI-X was a “double-wide” PCI

interconnect that allowed data transfer rates of up to 133MB/s.

As technology advanced, interconnect bandwidth demands and

requirements of very fast throughput rates from expansion cards

increased substantially. In 2004 PCI Express was created, which

offers data transfer rates to 16GB/s (up from 32MB/s of PCI -

a 500-fold increase in data throughput).

PCI and PCI Express slots are not compatible; therefore you

can’t interchange cards between these two slot types, but must

update the full backplane of your system.

PICMG 1.3 Specification

SHB (System Host Board) Express (aka PICMG 1.3) covers a

technology that is packaged with a host board using PCI

Express as the primary interface to the backplane. The same

board dimensions apply to PICMG 1.3 that apply to PICMG 1.0

(PCI/ISA) and PICMG 1.2 (PCI-X/PCI), however the backplane

must be completely changed to support the higher speeds of PCI

Express.

Why would I want to migrate from PICMG 1.0 to PICMG 1.3?

The first response is to avoid End of Life issues with your

components. Cards that are easily available today will become

harder and harder to find. It is best to make that full system

change now rather than to continue updating part by part until

you no longer have any options. It’s best to avoid that finality

by planning ahead and migrating your program to a new

technology that is ideal and well thought out for your

application. Many feel that the PCI bus is set to end sooner

rather than later, and will go the way of the EISA and ISA

busses.

The second reason would be for performance. The increased

data transfer rates will help you get more bang for your buck

and allow your end-customer to grow their feature set.
