    • A wireless power transfer system includes: a plurality of power transmitters, each of which transmits a microwave; and a rectenna base station which receives the microwave to generate power. The rectenna base station includes: a rectenna; and control section which specifies an identification code for identifying each power transmitter and generates a command signal to change a phase of the power transmitter specified by identification code so as to increase a power value received at the rectenna. Each of the power transmitters comprises: a plurality of transmission antenna elements, each of which transmits the microwave to the rectenna base station; and a phase controller which makes phase change of the microwave based on the command signal from the phase monitor and control section of the rectenna base station if the identification code matches a stored identification code.
    • 无线电力传输系统包括:多个功率发射器,每个发射器发送微波; 以及接收微波以产生功率的整流天线基站。 整流天线基站包括:整流天线; 以及控制部分,其指定用于识别每个功率发射器的识别码,并且生成用于改变由识别码指定的电力发射器的相位的命令信号,以增加在整流器天线处接收的功率值。 每个功率发射器包括:多个发射天线元件,每个发射天线元件将微波传输到直流天线基站; 以及相位控制器,如果识别码与存储的识别码相匹配,则基于来自直达天线基站的相位监视和控制部分的命令信号使微波相位变化。
