WIRELESS POWER TRANSMISSION DEVICE

摘要

A wireless power transmission device includes a power transmitter, a first transmission unit, a power receiver, a feedback regulator, a receive controller, and a second transmission unit. The power transmitter is for generating power, and the first transmission unit is for wirelessly transmitting power generated by the power transmitter. The power receiver is for receiving and rectifying the power from the first transmission unit. The feedback regulator is for receiving a feedback signal from the power receiver to generate an AC control signal. The receive controller is for receiving the control signal to generate a driving signal. The second transmission unit is for wirelessly transmitting the control signal to the receive controller.
