本文以一个电动汽车在线供电系统为例，设计并实现了一个沿着移动电动汽车的无线电能传输系统。电动汽车通过无线电能传输技术在道路上充电。介绍了逆变器、电源线、拾波器、整流器和调节器的电气和实用设计，以及针对大气隙的优化磁芯结构设计。此外，电动车辆的电动势屏蔽的建议。整个系统已经实施和测试。实验结果表明，在26 cm的气隙下，可获得100 kW的功率，功率转换效率为80%。
In this paper, the design and implementation of a wireless power transfer system for moving electric vehicles along with an example of an online electric vehicle system are presented. Electric vehicles are charged on roadway by wireless power transfer technology. Electrical and practical designs of the inverter, power lines, pickup, rectifier, and regulator as well as an optimized core structure design for a large air gap are described. Also, electromotive force shielding for the electric vehicle is suggested. The overall system was implemented and tested. The experimental results showed that 100-kW power with 80% power transfer efficiency under 26-cm air gap was acquired.
