带可切换中继线圈的三线圈无线电能传输系统互感识别与效率优化研究

One of the most difficult problems of the three-coil wireless power transfer (WPT) systems is that the receiving coil is hardly fully aligned with the transmitting and relay coils, which affects the efficiency of the practical system seriously as the coupling exists among the transmitting, relay and receiving coils simultaneously. Therefore, this article presents a new mutual inductance identifica...
