Original Abstract Submitted
A power transmission unit includes a clock generation circuit that generates a clock signal, a switch circuit that switches alternating-current power at a timing based on the clock signal, a power transmission antenna that wirelessly transmits the switched alternating-current power, and a transmission antenna that wirelessly transmits the clock signal. A power reception unit includes a power reception antenna that receives the power transmitted from the power transmission antenna, a reception antenna that receives the clock signal transmitted from the transmission antenna, and a rectification circuit that switches the power at a timing based on the received clock signal. A first correction circuit corrects the phase of the clock signal to reduce a phase shift between a phase of the alternating-current power input from the rectification circuit and a phase of the clock signal input from the rectification circuit.
