The power unit of the two-quad high voltage drive is mainly composed of rectifier diode, filter capacitor and IGBT. Each power unit is an H-bridge structure that outputs a set of SPWM waves.
The whole machine has several units per phase. Through the carrier phase shifting technology, the output voltages of each unit are superimposed to form a multi-level high voltage output. There is no need to output the filtering device, the current harmonics are small, and there is no damage to the cable and motor insulation. The figure shows output voltage waveform of each of the five units and the superposed voltage waveform.
When the motor is in the drag state, the energy flows from the rid through the rectification loop and the inverter loop to the motor, and the VFD works in the first and third quadrants. The input voltage and current waveforms are as shown.
The four-quad high voltage drive can perform energy feedback, and the power unit replaces the input rectifier diode with the IGBT with respect to the two-quad high voltage drives, realizing the energy bidirectional flow.
When the motor is in the power generation state, the DC bus voltage is greater than the input voltage, and the feedback control part inverts the DC voltage into an AC voltage, and the energy is fed back to the grid by controlling the voltage phase and amplitude. At this time, the energy flows from the motor to the grid through the inverter side and the feedback side. The inverter works in the second and fourth quadrants, and the feedback current and grid voltage waveform are as shown.
