2. Voltage Overlap Diagram
Each phase of AXPERT- HIVERT Series Medium Voltage Drive consists of multiple power units connected in series, and each power unit is
isolated by the secondary winding of isolating transformer. By changing the quantity of units in series, the phase-shift power supply can easily
obtain the output of different voltage level, without being subjected to the restriction of the power devices for their voltage resistance
performance. Assuming that each phase of an inverter rated 6.6kV consists of 6 power units and the rated voltage of power unit is 690V. the
phase voltage will be 3810V after connection in series (The corresponding line voltage is 6.6kV). Each phase of 11KV Inverter consists of 9
power units, the rated voltage of power unit is 710V, and the working voltage is 710V.
3. Structural Diagram of Power Unit
AXPERT-HIVERT Series Medium Voltage Drive consists of
multiple power units connected in series, and each power
unit is powered by the secondary isolating winding of the
input isolating transformer. The power unit is of AC-DC-AC
structure, equivalent to a low-voltage power source inverter
of 3-phase input single-phase output. As power units are
fully identical in structure and electrical performance, very
easy for maintenance and replacement.
The power unit receives the signal via optical fiber and adopts space vector sinewave pulse (PWM) to control the conductivity and disconnection
of Q1~Q4 IGBT, outputting single-phase pulse width modulation waveform. Each unit is only possible to have three states of output voltage.
When Q1 and Q4 are connected, the output voltage state of LI and L2 will be 1; when Q2 and Q3 are connected, the output voltage state of L1 and
L2 will be -1; and when Q1 and Q2, or Q3 and Q4 are connected, the output voltage state of L1 and L2 will be 0.

High-quality Current Input
Perfect Output Performance
Through phase-shift voltage dropping, the secondary winding of isolating transformer on input side will provide isolated power source to
each power unit. For 3.3kV, it is equivalent to 18-pulse, (24-pulse for 4.16kV, 36-pulse for 6.6kV, 54-pulse for 11kV) un-controlled rectifying
input. This eliminates most of the harmonic current caused by each power unit and greatly inhibit the generation of harmonic wave on grid
side.
The harmonic voltage and THD caused to electric grid by the inverter meets the most stringent requirements for THD as specified in IEEE
Std519-1992 and GB/T14549-93 (Quality of Electric Energy Supply Harmonics in Public Supply Networks). The inverter requires no
installation of filter, but it can protect the surrounding equipment from harmonic interference. The power factor within normal range of speed
regulation is over 0.95, so the power-factor compensation capacitor is not required.
Reduce the reactive input and decrease the supply capacity.
The units are connected in series and of PWM overlap output. Each phase consists of 6 units for 6.6kV series inverter, and 9 units for 11kV series.
This results in greatly reduced output of harmonic content, so that the output waveform is nearly perfect sine wave. In comparison with other
types of high voltage large-capacity drives, AXPERT- HIVERT Series MVD has following advantages:
No output filter required.
Able to drive common high-voltage motor without increasing the motor temperature or decreasing the motor capacity.
Motor cable is free of any length restriction.
Protective insulation of motor is free from the damage of dv/dt stress.
Service life of the equipment will not be shortened due to harmonic torque.
Product Characteristics
AXPERT- HIVERT Series Medium Voltage large-capacity drive is a type of medium voltage AC motor speed regulation drive. Our drive adopts
the advanced technology of series connection and wave overlap of the power unit, space vector sinewave PWM control. It also incorporates full
English operating interface and high-performance IGBT based modules , featuring in high reliability, superior performance and easy operation. It
can be used for a wide range of applications such as regulation, energy saving, soft startup and intelligent control of the fan, water pump,
compressors and other similar loads driven by medium voltage AC motor.

User-Friendly Interface
The user interface includes 3 indicators, 2 buttons. 1 LCD and 1 mini keypad. If the red indicator on the
left is bright, it indicates that the inverter main power is on and standby. If the green indicator is bright, it
indicates that the inverter is running. If the red indicator on the right is normally bright, it indicates that inverter
is incurred to fatal faults and shall be disconnected from the main power automatically. If the red indicator on the right
blinks, it indicates light fault, in which case the inverter may run continuously but requiring elimination of the fault.
Below the indicators is an industrial LCD display with 240x128 resolution and a mini keypad, on which 8-line characters
can be displayed. From the LCD display and keypad, you can perform all operations of the inverter.
By pressing PRG key, you can switch between four pages, sequentially as system status page, function setup page,
parameter setup page and fault logging page.
Advantage: No mechanical rotating component, long operating reliability, and easy upgrading of software.
Flexible Control Options
Five Options of Frequency Set
AVR (Automatic Voltage Adjustment) Function
PID Function
nLocal Control: Direct control from the button on cabinet door or
the keypad. This is the main control method.
nRemote I/O Control: Realize remote control by connecting to the
remote switch signal via the I/O board.
nHost Control: Isolated RS-485 port and adoption of standard
MODBUS RTU communication protocol. Able to connect with host
system like DCS for optimized coordination control.
nDirect command from main interface.
nSet by analog signal (4-20mA signal).
nSet by host computer via RS-485 port.
nMulti-speed set, suitable for the working conditions in cyclic change.
nIn event of closed-loop operation, it will be automatic set by built-in PID via computation.
According to output voltage feedback, the inverter can automatically
adjust the output voltage to make it free from the influence caused by
the change of grid voltage and loads, and protect the motor from
insulation damage due to long overvoltage or core overheating due to
high magnetic flux density.
Built-in full digital PID is provided for closed-loop control upon the
users' requirements and for realization of operation under constant
press or constant fluid flux. PID parameters can be adjusted online.
Current Limiting Function
Self-diagnosis Function
Instantaneous Power Loss Tracing Function
Other Characteristics
In event the output current of the inverter exceeds the preset value, the
inverter will automatically limit the current output to avoid overcurrent
protection incurred during acceleration or deceleration or due to
sudden change of the loads, thus to minimize the stop times of the
machine.
AXPERT-HIVERT MVD is provided with complete self-diagnosis
capability to monitor the system status online. In event of any fault, the
inverter will be automatically activated to take protective actions and
save the time, cause and location of the fault. This will help the
maintenance personnel find the cause and eliminate the fault quickly.
In event the electric grid is incurred to instantaneous power loss, the
inverter will control the motor to be under power-generating status and
keep decelerated operation. If the electric grid resumes to normal, the
inverter will immediately return to original operating status. The keeping
time is 10 msec and typical value of the fan load is 3 sec.
nHighly efficient, with the system total efficiency up to 96% or over.
nThe control power is simultaneously supplied by 415VAC.
nWide range of input voltage.
nFast braking function.
nResonance frequency avoidance.
nCustomized design available upon the user's request.

1. One Inverter drives one motor
When the inverter exits the operation, it may switch the motor into the grid via the by-pass loop, thus to ensure the continuity of the production activity. If vacuum contactor is selected for the switch K1, K2 and K3, the switching operation may be completed automatically.
Application Program
2. One inverter switches between two motors
To cut your investment, you may select this method if one inverter needs to switch between two motors, i.e. one in service and one on standby.
