WIRELESS POWER TRANSMITTER AND WIRELESS POWER TRANSMITTING METHOD

摘要

The present invention relates to a wireless power transmitting and receiving system of a magnetic resonance method and an impedance matching method in the wireless power transmitting and receiving system. Provided is the wireless power transmitting and receiving system capable of improving the efficiency of wireless power transmission and reception by precisely matching impedance by controlling a current value of a current loop near an antenna or a current flowing in the antennas of a wireless power receiver and a wireless power transmitter.
