Abstract Design of asymmetric coupling coils via coupled magnetic resonances is complicated in wireless power transfer (WPT), especially considering the uncertain effects of frequency split caused by the changes of asymmetric structure parameters. This issue constrains the development of the WPT technology. In this paper, the equivalent circuit model of asymmetric WPT system is established. Then the power and efficiency expressions of asymmetric coupling system are presented. Meanwhile, the influence of internal resistance and quality factor on frequency splitting is summarized. Finally, the experimental system is built to verify the theoretical analysis. The results not only prove the correctness of the proposed method, but also provide a beneficial reference for optimal control of WPT system with asymmetric coupled coil.

Key words： Wireless power transfer (WPT) asymmetric coupled coil frequency splitting coil resistance quality factor
