WIRELESS POWER TRANSMISSION AND RECEPTION APPARATUS HAVING RESONANCE FREQUENCY STABILIZATION CIRCUIT AND METHOD THEREOF |
摘要 |
A wireless power transmission apparatus and method for wirelessly transmitting power to a wireless power reception apparatus electromagnetically coupled to the wireless power reception apparatus and supplying power for loads of the wireless power reception apparatus is provided. The apparatus includes a power generator for generating power having a fixed oscillation frequency; a power transmission resonator, which has a resonance frequency identical to the oscillation frequency, for wirelessly transmitting the power generated by the power generator to the wireless power reception apparatus; and a power transmission resonance frequency controller for controlling the resonance frequency of the power transmission resonator in response to a change of the resonance frequency of the power transmission resonator.
