Abstract
Official abstract text for this publication.
Provided is a wireless power transmission apparatus and method. The wireless power transmission apparatus may include a coupling unit to couple a reflected signal with respect to a transmitted resonance power, and a resonance point detecting unit to scan a frequency of the reflected signal to detect a resonance point. A resonance frequency of the source resonator may be controlled using the detected resonance point.
First claim
Opening claim text (preview).
What is claimed is: 1. A wireless power transmission apparatus comprising: a source resonator to transmit resonance power to a target resonator; a coupling unit to couple a reflected signal with respect to the transmitted resonance power; a resonance point detecting unit to scan a frequency band of the reflected signal, verify an amplitude of the reflected signal corresponding to the frequency band, and determine a coupling frequency based on the amplitude, wherein the source…
