Abstract

A reception antenna includes a reception coil which receives a power signal. A rectification circuit rectifies an alternating current flowing to the reception antenna. A smoothing capacitor smoothes an output of the rectification circuit. A waveform stabilizer is enabled when a power receiver satisfies a predetermined condition and shifts a parallel resonance frequency of the reception antenna.
