Abstract
A power receiver includes a secondary-side resonance coil including a resonance coil part to receive power from a primary-side resonance coil by magnetic resonance; a capacitor in the resonance coil part of the secondary-side resonance coil; a series circuit of first and second switches connected in parallel with the capacitor; a first rectifier connected in parallel with the first switch, and having a first rectification direction; a second rectifier connected in parallel with the second switch, and having a second rectification direction opposite to the first rectification direction; a detector to detect a waveform of a power supply supplied to the secondary-side resonance coil; and a controller to adjust the waveform, and a phase difference between first and second signals to switch on and off the first and second switches, respectively, to adjust the power to be received by the secondary-side resonance coil.
