摘要
针对在无线电能传输(WPT)系统中负载的变化、接收线圈相对位置的变化和输入电源电压波动对输出电压影响的问题,采用三线圈结构,引入开关控制电容(SCC)补偿结构,通过调节SCC结构中双向开关的占空比,实现了输出恒压控制,仿真和实验结果验证了该方法的有效性。
Aiming at the problems that change of load and the relative position of receiver coils and fluctuations of input supply voltage influence on the output voltage in wireless power transfer（WPT） system,the three-coil structure is adopted and switch control capacitor（SCC） compensation structure is introduced.By adjusting duty cycle of bidirectional switch in SCC structure, the output constant voltage control is realized.The effectiveness of the method is verified by the simulation and experimental results.
