Inverters ( 20, 30 ), based on signals PWM 1, PWM 2 from a control device ( 70 ), generate a commercial AC voltage Vac across neutral points (N 1, N 2 ) of 3-phase coils ( 12, 14 ). A Y-capacitor ( 84 ) for removing noise is connected to a load ( 80 ) outside the vehicle receiving the supply of the commercial AC voltage Vac. A relay (RY 3 ) connected in series with a leakage detecting device ( 60 ) is provided inside the vehicle. The relay (RY 3 ) is turned off when a plug ( 82 ) of the load ( 80 ) outside the vehicle is connected to a connector ( 50 ), and prevents a leakage current from flowing via a ground.
