APPARATUS AND METHOD OF MATCHING IN A SOURCE-TARGET STRUCTURE
First Claim
1. An apparatus for controlling matching in a source-target structure that transmits and receives resonance power, the apparatus comprising:
- a target resonator to receive resonance power through magnetic-coupling with a resonance power transmitter;
a rectifier to rectify the resonance power to generate a DC voltage, and to provide the DC voltage to a load;
a load sensor to detect an impedance of the load and a variation in the impedance of the load; and
a target communicating unit to transmit information associated with the variation in the impedance of the load to the resonance power transmitter.

Abstract
Provided is a source-target structure matching controlling apparatus and method that may perform matching control of a source-target structure while resonance power is transmitted and received through the source-target structure. The source-target structure matching controlling apparatus may include a target resonator to receive, from a resonance power transmitter, the resonance power through a magnetic-coupling, and a rectifier to rectify the resonance power to generate a DC voltage, and provide the DC voltage to a load. The source-target structure matching controlling apparatus may detect an impedance of the load and a variance in the impedance, and may transmit, to the resonance power transmitter, information associated with the variance in the impedance of the load.
