Abstract
A non-contact charger aims to control transmitted power efficiently. The non-contact charger includes a transmitting coil, an inverter circuit, a receiving coil, and a transmitted power control circuit. The inverter circuit outputs the transmitted power to the transmitting coil. The receiving coil receives power as received power from the transmitting coil. The transmitted power control circuit drives the inverter circuit at a frequency higher than maximum received power frequencies at which the received power has one or two maximum values.
