Original Abstract Submitted

A wireless power receiver receiving power from a wireless power transmitter is provided. The receiver includes a resonance circuit, a rectifier circuit, and a driver circuit. The resonance circuit includes first and second coils and a first capacitor. The rectifier circuit includes first and second rectifier circuits. The first rectifier circuit includes first through fourth MOSFETs. Sources of the first and second MOSFETs are connected to ends of a resonator including the first coil and the first capacitor. Sources of the third and fourth MOSFETs are connected to ground. The driver circuit is connected to gates of the first through fourth MOSFETs, When the driver circuit switches off the first and second MOSFETs and switches on the third and fourth MOSFETs, as currents are induced in the resonator and the second coil, the resonance circuit receives the wireless power, and the current induced in the second coil is rectified by the second rectifier circuit.
