Martin, President of Diversified Technology, Inc.As we at
Diversified Technology complete our fortieth year in operation, I
think back on many of the customersand programs we have been
fortunate enough to serve with our products and service offerings.
Our work hasranged from PCI and ISA based single board computers
used as industrial controls at a canning plant to workingdirectly
with the dedicated men and women of our armed forces in providing
them with rugged computing andmobile power systems. All of our
customer relationships have molded us throughout these forty years
not onlyin what we design and manufacture as a product, but also in
how we conduct our daily business with thesecustomers and keep
their success as our main focus.This publication is part of how we
conduct that daily business. It is distributed to our growing list
of existing andpotential customers in order to help educate you on
a number of items we have learned through our years ofdevelopment
work. We dont want to just sell you a product with the assumption
you can resolve, if needed, anypossible operating intricacies on
your own. DTI has a goal of 100% customer satisfaction which
requires asubstantial effort on our part to provide full support
with the products we sell. We hope these articles from ourteam

interfaces, port 0/1 on 1936-B will be in the discarding state as
it sees the highest path cost to root. An interface in discarding
state will only pass spanning-tree BPDU packets and drop all other
traffic. The role for port 0/1 is alternate which indicates that
this port will provide an alternate path to root should interface
failure occur on the current root path. This enables RSTP to react
to link failures very quickly providing a redundant path to the
upstream switch usually within 1-3 seconds after an uplink failure.
During normal operations, the path from the Slot 9 host to the
gateway switch SW-A would be through port 0/18. If 0/18 where to
fail, RSTP would change the 1936-B port 0/1 state from discarding
to forwarding and MAC address tables would be cleared and
re-populated with new path information. Packets destined for

and then on to SW-B and SW-A. Figure 1: RSTP Operation Page 9

Turbine Synchronous Synchronous Inverter Inverter 12kW Grid-Tie
Inverter 6kW Grid-Tie Inverter The Gale Series of Inverters
Diversified Technology, Inc.s Gale Series of wind turbine inverters
are variable input voltage and frequency, high 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 pure sine,
clean filtered power that can be sold to the utility. Managed by
DTIs 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 even at minimal turbine revolutions, and
many other features designed to meet the specific needs of the wind
power market. DTIs Soft Grid Technology allows the inverter to
continue to produce the maximum amount of power even during wind
gusts that would otherwise cause over voltage on the grid. This is
useful in rural locations during light local d loading conditions.
This maximizes profits for the operator while preventing in
annoying system resets. m/w s.co The Gale Series of Grid-Tie
Inverters tim are fully-compliant with UL 1741 w.d The Gale Series

Stacking with One Turbine Gale-12 DTIs Wind Turbine Inverter with
up to 12kW of Power OutputBecause Gale inverters are
transformerless, they inject a largevarying DC offset back onto
their input. For single invertersthis is the lowest cost and most
efficient design. However, whenstacking inverters with a common
input, an isolation transformer(which blocks DC) is required to
keep the inverters fromdisturbing each other. Unlike our
competitors, because ourinverters contain an integrated rectifier,
this isolation transformercan be installed on the input side of the
inverter instead of thegrid side. This means that power will only
be lost in thetransformer when the wind is blowing. Another problem
withinstalling the transformer on the grid side is that it defeats

there are no losses from sendingthe input power through a second

turbinecontroller, then do it just like with the AC input inverters

17. Providing a Cohesive Approach to Embedded Computing and
Power SolutionsGenerator StackingSometimes customers ask us about
stacking small turbinestogether and using one inverter. The Gale
inverter has no trou-ble with this, but it is not an easy
arrangement to get to work. Atthe very least, with nothing else to
synchronize them, the fastestturbine will tend to motor the
slowest. However, in most casesthe AC generators will never start
because they are out of phase.However, if each small turbine is
given its own rectifier then thecommon DC can be fed to a Gale-DC
inverter. This will workbest if all of the small turbines are the
same model and receivethe same amount of wind. Figure 7:
Neighborhood Wind Example 1 Figure 6: Stacking Small

stacked inverters) can be sharedbetween multiple houses, with
several investors dividing theprofits. The most straight forward
implementation would be toconnect the Gale inverter behind its own
power meter, then splitup the profits paid by the utility company.
However this requiresmaking special connection arrangements with
the utilitycompany. It is also possible to connect the inverter to
one of thehouses and monitor the inverters output, then use the
utilityskWh rate to determine how much money to distribute to
theother investors. This gets more complicated if the rate
changesat different times of day, however 3rd party power meters
