TRANSMITTER AND RECEIVER IN A WIRELESS POWER TRANSMITTING SYSTEM, AND METHOD FOR THE TRANSMITTER AND RECEIVER TO WIRELESSLY TRANSMIT/RECEIVETRANSCEIVE POWER

摘要

A transmitter in a wireless power transmitting system according to the present invention, a transmitter in a wireless power transmitting system includescomprises: a Tx power converting unit for converting DC voltage into a first AC voltage and amplifying the converted first AC voltage in order to convert it to a second AC voltage; a Tx matching circuit for matching impedance by usingto a receiver that receives the second AC voltage in order to transmit the second AC voltage; a TX resonator for resonating the second AC voltage as a resonance wave in order to transmit the second AC voltage to the receiver; and a Tx control unit for determining an amplification rate of the first AC voltage and controlling the Tx power converting unit in order to convert the first AC voltage into the second AV AC voltage according to the determined amplification rate.
