  • Wireless power transmitter utilizing phase and amplitude control algorithm and wireless power receiver
    Patent number: 10516302
    Abstract: A wireless power transmitter includes a signal generator for generating power signals, a modulator for modulating a phase of a power signal to be time reversed based on beacon signals received from the wireless power transmitter and modulating an amplitude of a power signal to be amplified, a controller for providing a phase and amplitude control algorithm to be performed by the modulator, and an antenna unit for transmitting the power signals and receiving the beacon signals. The wireless power transmitter controls the amplification of amplitudes by using the phase and amplitude control algorithm, thereby improving wireless power transmission efficiency. In addition, the wireless power transmitter includes a multiple polarization antenna to enable high-efficiency wireless power transmission, regardless of a direction of the power signals and a direction of polarization.
