Abstract

A resonance power generator is provided. The resonance power generator includes an alternating current/direct current (AC/DC) rectifier to rectify an input signal of an alternating voltage and an AC generator to generate an AC signal based on the rectified signal that is output from the AC/DC rectifier. The resonance power generator may also include, for example, a control unit to control a frequency of the AC signal, a filter unit to remove a spurious signal or a harmonic element included in the AC signal, a voltage/current amplifier to amplify the AC signal, and a source resonator to transmit a power to a target resonator.
