METHOD AND APPARATUS FOR WIRELESS POWER RECEPTION AND METHOD AND APPARATUS FOR WIRELESS POWER TRANSMISSION AND WIRELESS POWER TRANSMISSION SYSTEM

摘要

The present invention relates to a wireless electric power receiving device and method, a wireless electric power transmitting device and method, and a wireless power transmitting system which include: a source resonator which wirelessly transmits electric power to a target resonator by mutual resonance with the target resonator; an electric power supplying part which supplies electric power to the source resonator; and a matching part which matches output impedance of the electric power supplying part with input impedance of the source resonator by connecting a passive component with the electric power supplying part in parallel or serially, based on the characteristics of the electric power supplying part.
