Patent ID: 8611111

Claim:
A resonance power generator comprising: an alternating current/direct current (AC/DC) rectifier configured to rectify an input signal of an alternating voltage; an AC generator configured to generate an AC signal using the rectified signal output from the AC/DC rectifier; a control unit configured to control a frequency of the AC signal; a filter unit configured to remove a spurious signal or a harmonic element included in the frequency-controlled AC signal; a passive voltage/current amplifier configured to passively amplify the filtered AC signal; a feedback loop configured to receive an output of the passive voltage/current amplifier, to detect an amount of change in a value of the AC signal that passes through the passive voltage/current amplifier, and to feed back the value of the detected amount of change to the control unit, wherein the control unit compensates the AC signal input to the passive voltage/current amplifier based on the value of the amount of change; and a source resonator configured to transmit power derived from the passively amplified AC signal to a target resonator.
