<p>When an earth faulting has occurred in a driving device for driving motor (M1), an electric potential of a vehicle earth is changed. Therefore, in a DC/DC converter (100), a high-voltage noise intrudes a high-voltage detector (140) through a connection node of a Y capacitor constituted by a pair of capacitors (C1, C2). When the earth faulting of the driving device has occurred, the control device lowers the direct-current side voltage of the inverter in the high-voltage system to reduce the quantity of the high-voltage noise intruding the high-voltage detector (140).</p> |
