| 主权项 | 1. A wireless power transmission apparatus comprising: a transmitter configured to wirelessly transmit electric power while changing a transmission resonant frequency of the transmitted electric power; and a receiver configured to receive at least the transmitted electric power while changing a reception resonant frequency of the receiver, wherein the receiver includes (a) an antenna configured to receive the transmitted electric power, (b) a rectifying unit configured to rectify the received transmitted electric power to a transmission voltage and feed the transmission voltage to an adjusting circuit, and (c) a control unit configured to control the adjusting circuit to adjust an antenna resonate frequency to maximize the voltage reception, andwherein the control unit is configured to change the resonant frequency of the receiver to the same resonant frequency of the transmitted electric power. | ||
