摘要：When a failure detection part detects a failure in an inverter circuit in a firstpower supply system, a drive control part stops the inverter circuit from driving a motor.An on/off control part turns off a first power supply relay of a power supply on/off part.Under a state that the inverter circuit stops a motor driving operation, a first coil set of

the motor generates an induced voltage by rotation caused by an external force. Theinduced voltage is regenerated to a battery from the inverter circuit through a secondpower supply relay and a parasitic diode of the first power supply relay. Thus, circuitelements in the power supply system, which is failing, are protected from breaking down.
