In the wireless charging process of electric vehicles, unmanned aerial vehicles (UAVs), inspection robots and other electrical equipment, coil misalignment is inevitable due to human factors, external factors such as airflow during landing and other positioning problems, which severely limits its application. Accurate localization of the receiver coil can effectively reduce or even avoid the misalignment, but the traditional localization techniques may not be suitable for the complex electromagnetic environment of wireless charging system. In this paper, a receiver localization method based on mutual inductance disturbance for wireless power transfer (WPT) system with a relay coil is proposed. This method can achieve two-dimensional (2-D) localization of the receiver coil, and it will be more effective for high-temperature superconducting (HTS) WPT system with larger transmission power. The simulation and experiment are carried out to locate the receiver coil, and the results verify the feasibility of the proposed method.

基于互感扰动的无线充电系统接收端定位策略


在电动汽车、无人机、巡检机器人等用电设备的无线充电过程中，由于人为因素、着陆时气流等外界因素以及其他定位问题，不可避免地会出现线圈错位的情况，严重限制了其应用。接收线圈的精确定位可以有效减少甚至避免错位，但传统的定位技术可能不适合无线充电系统复杂的电磁环境。本文提出了一种基于互感干扰的中继线圈无线电力传输（WPT）系统接收器定位方法。该方法可以实现接收线圈的二维（2-D）定位，对于传输功率较大的高温超导（HTS）WPT系统将更加有效。通过仿真和实验对接收线圈进行定位，结果验证了该方法的可行性。
