Abstract
An apparatus and a method for receiving power wirelessly, and an apparatus and a method for transmitting power wirelessly are provided. The apparatus for transmitting power wirelessly includes: a source resonator configured to transmit power wirelessly to a target resonator through a mutual resonance with the target resonator; a power supply unit configured to supply power to the source resonator; and a matching unit configured to connect a passive device to the power supply unit in series or in parallel to match an output impedance of the power supply unit and an input impedance of the source resonator.
