摘要： 为实现负载阻值发生改变后, 电动汽车进行无线充电时仍能达到最优效率和恒压输出, 在负载侧接入同步Sepic 变换器, 对不同负载阻值进行识别, 通过改变占空比的方式进行阻抗匹配, 实现传输效率最优。利用移相全桥对整流器的移相角进行闭环控制实现恒压输出。最后, 利用 Matlab / Simulink 软件进行仿真实验, 证明了该阻抗匹配方式和闭环控制方案的可行性。

Abstract: To achieve optimal efficiency and constant voltage output when the electric vehicle is charged wirelessly even after the load resistance value is changed, a synchronous Sepic converter is connected on the load side to identify different load resistance values, and impedance matching is performed by changing the duty cycle to achieve optimal transmission efficiency. The phase shift angle of therectifier is closed-loop controlled using a phase shift full bridge to achieve constant voltage output. Finally, simulation experiments using Matlab / Simulink software demonstrates the feasibility of this impedance-matching method and closed-loop control scheme.
