    摘要: An equipment and method for detecting electrical leakage in an electric vehicle. For detecting occurrence of leakage in an alternating-current motor for driving the vehicle, a source-side transistor of an inverter is turned ON and a sink-side transistor is turned OFF. When leakage occurs in the motor, there arises an electrical path to an electric leakage detector through the grounded portion from the transistor on the source-side, the motor winding, and the leakage portion. Due to a current flowing in the electrical path, the electrical leakage detector determines that the leakage is present, and the result is notified to the ECU (electronic control unit). On the contrary, the source-side and sink-side may preferably be turned OFF and ON respectively. It is unnecessary to turn ON all the source-side or all the sink-side transistors. The leakage in the motor can be detected without misinterpreting noise on the battery-side as viewed from the inverter.
