摘要：In a driving system for vehicles having a high voltage main battery for a vehicledrive motor and a low voltage accessory battery for accessory devices such as a radioreceiver, a three-phase inverter circuit for driving the vehicle drive motor and a DC-DCconverter are connected to the main battery through electromagnetically shielded highvoltage power lines. The DC-DC converter supplies a low voltage electric power to adriver circuit for switching on and off the inverter circuit. Switching noise voltages causedby switching operations in the inverter circuit, the driver circuit and the DC-DC converterare restricted from being superimposed on low voltage power lines connecting theaccessory battery to the accessory devices.
