Abstract:
A wireless power transmitter may comprise: a signal generation unit which generates a differential signal; an amplifier which amplifies the differential signal with a predetermined gain; a resonance unit which generates an electromagnetic wave using the amplified differential signal and radiates the same; and a signal adjustment unit which senses at least one of the current and the voltage of the amplified differential signal at the input terminal of the resonance unit, and adjusts at least one of the phase and the amplitude of the differential signal output from the signal generation unit, on the basis of the result of the sensing.
