介绍了一种强耦合四线圈无线电能传输系统。发送器(TX)和接收器(RX)线圈均采用保形架构。因此，实现了共面线圈之间的高互耦系数。进一步提高了一次、二次线圈的品质因数。建议的WPT系统具有紧凑的结构，适用于生物医学应用，当TX和RX之间的距离为10 mm，共振频率为13.56 MHz时，测量效率高于79%。用HFSS对所设计的系统进行了10 mm人体组织介质的模拟，得到了55.1%的功率转换效率。仿真结果也得到了实验的验证。©2016威利期刊，Inc.微波技术通讯58：1861-1866,2016
Strongly coupled four‐coil wireless power transfer (WPT) system is presented in this letter. Conformal architecture is used for both transmitter (TX) and receiver (RX) coils. Thus, a high mutual coupling coefficient is achieved between the coplanar coils. Furthermore, the quality factors of primary and secondary coils are improved. The proposed WPT system features a compact structure for biomedical applications and provides a measured efficiency greater than 79% when the distance between the TX and RX is 10 mm at a resonance frequency of 13.56 MHz. The designed system is also simulated for 10 mm human tissue medium using HFSS, which generates a power transfer efficiency of 55.1%. The simulated results are also verified by experimentation. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1861–1866, 2016
