Drive Motor "A" Inverter Voltage Sensor(VH) Circuit Voltage Below Threshold (P0D2D16,P0D2D17,P0D2D1F)
DESCRIPTION The inverter contains a three-phase bridge circuit, which consists of 6 power transistors (IGBTs) each for the generator (MG1), motor (MG2) and rear motor (MGR). The inverter converts high-voltage direct current from the HV battery into three-phase alternating current for the generator (
