Abstract:
A wireless power transmission apparatus includes a source resonator configured to transmit an output power from which a harmonic component has been cancelled to a wireless power reception apparatus by resonating with a target resonator of the wireless power transmission apparatus, and a resonant power generator configured to differentially input a first input signal and a second input signal to the source resonator, and cancel the harmonic component of the output power.
