The DC power is mainly composed of rectifier, limiting reactance, and IGBT module. The main function is to convert about 380V three-phase AC current into 500V DC through three-phase full wave rectification. The current limiting reactance of the DC output provides a constant current for the IGBT inverter circuit to meet the working requirements of the parallel IGBT inverter Circuit, en vervolgens wordt het naar de omvormer gesloten door middel van secundaire rectificatie .
