D02

The power will input dc DC750V by input inductance, pre-charging circuit and supporting capacitance to supply three phase inverter bridge circuit. The modulation voltage of the PWM is generated by IGBT inverter bridge which controls the inverter part when the external control signal is given. The three-phase PWM wave voltage has been filtered by the sine wave to output stable three-phase 380V / 50Hz sine wave, which can power the air compressor of subway vehicles.
