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, and then it is transported to the inverter cabinet through secondary rectification.
