WIRELESS POWER TRANSMITTER AND WIRELESS POWER RECEIVER USING PHASE AMPLITUDE CONTROL ALGORITHM

摘要

A wireless power transmitter according to the present disclosure includes: a signal generation unit for generating a power signal; a modulation unit for performing the time reversal of the phase of the power signal by referring to a beacon signal from a wireless power receiver and modulating the amplitude to amplify the same; a control unit for providing a phase amplitude control algorithm to be performed by the modulation unit; and an antenna unit for transmitting a power signal and receiving a beacon signal. The wireless power transmitter according to the present disclosure can control amplitude amplification through a phase amplitude control algorithm to improve wireless power transmission efficiency. In addition, the wireless power transmitter includes a multi-polarized antenna, enabling high efficiency wireless power transmission regardless of the direction of the power signal and the direction of the polarization.;COPYRIGHT KIPO 2017
