<p>When a ground fault has occurred in a drive device for driving a motor (M1), since vehicle-earth potential fluctuates, high noise infiltrates a high-voltage detection unit (140) via the connection point of a Y capacitor comprising a pair of capacitors (C1, C2) within a DC/DC converter (100). In the present invention, a control device decreases the amount of high-voltage noise infiltrating the high-voltage detection unit (140) by decreasing DC-side voltage of an inverter in a high-voltage system when a ground fault in the drive device has arisen.</p> |
