摘要：

With the development of wireless power transfer (WPT) technology, more and more attention has been paid to supplying electricity to multiple loads simultaneously. In a multi-load WPT system, the cross coupling between the receiving coils will detune the system, resulting in a decrease of transmission efficiency at the resonant frequency. This paper firstly analyzes the influence of cross coupling on transmission efficiency, and proposes a "T" type impedance matching network based on RBF neural network. The proposed method adjusts the capacitance in the matching network in real time according to different loads, realizing the adaptive matching of system and load. Finally, an experimental setup was built for the proposed method, and the results show that when the cross coupling is the greatest, the system transmission efficiency increased from 34% to 78%. © 2021, Electrical Technology Press Co.
