GBP-H Four Quadrant Medium Voltage Variable Frequency Drive Principle
It is a special Medium Voltage Variable-Frequency Drive developed and produced by our company according to the operation requirements of Mine Hoist. This drive is based on the technology of series power unit and stack wave, high performance vector control technology as the core. This drive consists of rectifier phase shift transformer, power unit and control part.
The output voltage range from 3 kV to 10 kV, different output voltage is with different number of power units, 3 kV has 9 units, 6 kV has 15 units, 10 kV has 24 units, power units on each phase is connected in series and stack wave to increase voltage, the power units on the three-phase is connected by Y type, outputing rated voltage directly.
Powert units
The overall topology of the power unit is AC-DC-AC three-phase full-bridge rectifier, single-phase Inverter output structure. Inside the power unit contains complete Energy Feedback circuit, DC filter circuit, inverter circuit, both rectifier side and inverter side are using controllable power electronic components IGBT, DC link is using electrolytic capacitance. Each power unit is equivalent to a AC-DC-AC voltage source type outputing single-phase Low Voltage Vfd. The control board of power unit completes the high-speed communication with the control system through the optical fiber, control the on-off of the IGBT, outputs the PWM waveform, and collects the fault and the state uploading to the control system, completes the work of the whole unit. Power unit is Modular design, which can be easily disassembled and installed integrally for convenient on-site fault handling.
Excellent product performance
