2.2 Operating Principle and System Component
2.2.1 System Working Principle
The ACH200 series of high voltage AC drive systems are "high-high", voltage-source AC
drives. The series H-bridge high voltage AC drive speed control system is based on an output of
6kV with 5 units per phase (for 10kV, 8 units per phase).
The 6kV grid voltage in the diagram feeds the phase shifting transformer directly, which has
15 separate three-phase low-voltage windings on the secondary side. Each three-phase low-voltage
winding feeds a low-voltage single-phase AC drive (called an H-bridge or power unit), whose circuit
diagram is shown in Figure 2-2. In the example given in Figure 2-2, each of the three phases output
to the motor is connected in series by five power units, making a total of 15 power units for the three
phases, resulting in a variable voltage, variable frequency power supply with three proportional and
adjustable voltages and frequencies. It can directly drive three-phase asynchronous motors up to 6
kV.
If a voltage of 10 kV is required, the number of power units in series per phase can be increased.

Figure.2-3
The input power supply terminal R/S/T is connected to the three-phase low-voltage output of
the transformer secondary coil, which is rectified by a three-phase full bridge to charge the DC bus
and then inverted into a single-phase AC output via the H-bridge. The single-phase output of the
power unit is: ACI/ACO.
The unit control circuit controls the work of the whole unit by receiving signals from the main
control system, while the power unit also transmits its own voltage, fault information and status
information back to the main control system via optical fibre to realise the monitoring of the power
unit.
The power unit has a unit bypass function, one for IGBT bypass and one for relay bypass
(optional). When a unit fails, the power unit can be bypassed automatically to ensure that the
frequency control system continues to work normally.
2.2.2 System Component
The components of the ACH200 series high voltage AC drive speed control system include
an integrated AC drive cabinet, and a bypass cabinet (optional), as shown in Figure 2-4.

Chapter 2 Product Information ACH200 Series High Voltage Variable Frequency Speed Control System Operating Manual
13
Figure.2-4
1) Transformer cabinet composition:
The transformer cabinet contains mainly high-voltage isolated phase shifting transformers. In
the case of a 6kV high voltage frequency conversion system, for example, each phase of the power
cabinet consists of five power units. These units are powered by the secondary side of the isolation
phase shifting transformer, and the secondary sides differ by a phase difference in turn, allowing for
multiplexed series rectification. In the primary side of the phase shifting transformer, the current
waveform of each converted secondary side is very close to a sinusoidal waveform after
superposition, so that the harmonic interference to the grid is very low and fully meets the
requirements of various international and domestic standards including IEEE 519-1992 and
GB/T14549-93. At the same time, the power factor of the system is improved.
The transformer cabinet also includes temperature measurement points for the temperature
monitoring controller, which monitors the temperature of the windings in a real-time cycle. The
transformer temperature monitoring controller will promptly feedback information about
transformer over-temperature or transformer faults to the control cabinet, ensuring reliable operation
of the transformer.
2) Power cabinet composition:
The power cabinet is the core part of the main circuit of the AC drive power, it consists of
several identical power units, the output voltage of each power unit is superimposed in series to
form the three-phase voltage output to the motor.
Taking a 6kV high voltage AC drive speed control system as an example, each phase contains
5 power units and the output voltage of each power unit is AC 690V, the phase voltage is 5 x 690V,
i.e. 3450V, and accordingly, its line voltage is 6kV.

Chapter 2 Product Information ACH200 Series High Voltage Variable Frequency Speed Control System Operating Manual
14
If the device designed is a 10kV frequency-controlled system, it contains 8 power units in each
phase.
By using an optimised PWM (Pulse Width Modulation) control technology with independent
intellectual property rights, the voltage waveform output to the motor is very close to a sinusoidal
waveform with low harmonic content and small dv/dt. No additional filters are required and the
output can be directly to an asynchronous motor or a synchronous motor with no requirement for
the length of the cable from the AC drive to the motor. Communication between the power unit and
the control cabinet is via high-speed and reliable optical fibre, which effectively avoids
electromagnetic interference and increases the reliability of the system.
3) Control cabinet composition:
The control cabinet is the core of the whole high voltage variable frequency speed control
system, it decides and controls the action of each power unit according to the user's operation and
setting locally or remotely, and collects the voltage and current analogue quantities in the system,
and each switching quantity, after logic processing and calculation, to further drive the motor and
meet the output requirements.
The control cabinet includes isolation transformers, low voltage devices, the whole control
board, IO board, fibre optic board and LCD operating human-machine interface. Of these, all
calculations are carried out in the DSP control board. The control core is a professionally designed
DSP (Digital Signal Processor) supplemented by FPGA (Field Programmable Gate Array), their use
not only allows for high speed calculations and complex control functions, but also greatly
simplifies the design of the control circuit and improves the reliability of the control system.
4) Bypass cabinet:
The bypass cabinet is optional. Without the bypass cabinet, the high voltage input and output
lines can be connected via terminals in the transformer cabinet.
If bypass cabinets are used, either manual bypass or automatic bypass can be selected and the
corresponding bypass cabinets are described as follows:
i. Manual bypass cabinets:
The bypass cabinet in manual bypass mode is mainly composed of isolation knife gate, its
main function is to provide high voltage power supply for high voltage motors directly from the
grid when the high voltage AC drive is overhauled, without affecting the user's use. When in use,
it can be switched between AC drive operation and industrial frequency operation.

Figure.2-5
In the manual bypass cabinet in the diagram, there are three high-voltage disconnect switches.
To ensure that no power is back-fed to the AC drive output, QS2-a and QS2-b use a double-throw
disconnect switch to achieve mechanical interlocking. When QS1 and QS2-a are closed and QS2-b
is disconnected, the motor runs at variable frequency; when QS1 and QS2-a are disconnected and
QS2-b is closed, the motor runs at industrial frequency, at which time the AC drive is isolated from
the high voltage for easy access, maintenance and commissioning.
This system consists of high voltage cabinet, manual bypass cabinet, high voltage AC drive
and high voltage motor, of which the manual bypass cabinet and high voltage AC drive are provided
by Veichi Electric (the high voltage cabinet is already available in the original system).
ii. Automatic bypass cabinets:
The bypass cabinet in the automatic mode mainly includes vacuum contactors, isolation cutters
and other equipment, which can be controlled automatically without manual operation through the
control system of the control cabinet and, in the event of a system failure, the three-phase output of
the AC drive to the motor is automatically removed and switched to direct power supply from the
grid, without causing a system shutdown.
