Patent ID: 8716899

Claim:
A wireless power transceiving system, comprising: a power transmitting apparatus which converts power into a resonance wave and transmits the resonance wave; and a power receiving apparatus which receives the transmitted resonance wave, and converts the resonance wave into DC power, wherein the power receiving apparatus comprises a parallel resonant rectifier circuit that is impedance matched with impedance generated in the power receiving apparatus by parasitic components at a frequency of the resonance wave, wherein the parallel resonant rectifier circuit comprises: a first diode in which an anode is connected to a first terminal of the reception resonator and a cathode is connected to a first output node; a second diode in which a cathode is connected to the first terminal of the reception resonator and an anode is connected to a second output node; a first capacitive element which is connected to a second terminal of the reception resonator and to the first output node; and a second capacitive element which is connected to the second terminal of the reception resonator and to the second output node; wherein the first diode and the second diode generate the parasitic components at the frequency of the resonance wave, and capacitive values of the first capacitive element and the second capacitive element are specified to counter the impedance generated in the power receiving apparatus by the parasitic components.
