Abstract
A first converter performs power conversion and outputs AC power. The AC power outputted from the first converter is supplied to a first coil. The first coil is magnetically coupled with a second coil, and the AC power is transmitted from the first coil to the second coil. A second converter is connected to the second coil, and converts the AC power transmitted to the second coil to DC power and supplies the DC power to a load. A first control unit controls the first converter so as to alternately switch between a first state of outputting rectangular wave voltage which cyclically changes and a second state of outputting constant reference voltage, on the basis of required power of the load.
