METHOD AND APPARATUS FOR IMPEDANCE MATCHING USING RESONATOR ISOLATION IN WIRELESS POWER TRANSMISSION SYSTEM

摘要

An impedance matching method and apparatus using an isolated resonator in a wireless power transmission system are disclosed. A wireless power transmission apparatus according to an embodiment includes a switching unit that turns on/off a connection of a source resonator and a power supply unit; And a controller that estimates the distance between the source resonator and the target resonator to match the impedance of the source resonator.
