Abstract

A wireless power receiver is disclosed. The wireless power receiver comprises: a resonance tank for receiving magnetic resonance-type wireless power; a rectifier including a diode bridge and a first switch connected to both ends of any one diode for forming the diode bridge, so as to rectify wireless power received by the resonance tank and supply the rectified wireless power to a load; and a controller controlling the first switch so as to operate the rectifier as a full-wave rectifier or a half-wave rectifier.

Claims4

Dependent claims

A wireless power receiving unit comprising:

a resonant tank configured to receive wireless power in a magnetic resonance manner;
and
a rectifier configured to rectify the wireless power received by the resonant tank and supply a rectified current to a load, the rectifier comprising a diode bridge, a first switch connected across any one of diodes constituting the diode bridge, a bypass capacitor configured to prevent some current from being supplied from the resonant tank to the load, and a second switch connected to the bypass capacitor and configured to bypass some current supplied from the resonant tank to the load by the control of a controller;
wherein the controller is configured to control the first switch and the second switch based on a predetermined reference voltage and the output voltage of the rectifier, respectively.
