Abstract
A circuit comprises a two-way switch and an inductor and is disposed between an ac power source and a rectifier so that the circuit provides a voltage higher than the source voltage. The unit provides a high voltage dc power to charge a battery of an electric vehicle. If the inductor is accurately grounded, the circuit stops the flow of dc current thus preventing electric corrosion in the vehicle body.
