METHOD AND APPARATUS OF WIRELESS POWER TRANSMISSION FOR CANCELLING HARMONICS NOISE

摘要

Disclosed are a wireless power transmission method and an apparatus for cancelling a harmonic noise. The wireless power transmission apparatus according to an embodiment of the present invention comprises a resonant power generation unit and a source resonator. The resonant power generation unit can cancel harmonic components of output power by differentially inputting a first input signal and a second input signal in the source resonator. The source resonator can transmit the output power from which the harmonic components have been canceled to a wireless power reception apparatus by resonating with a target resonator.
