| 摘 要： | 为解决采用感应耦合电能传输(ICPT)技术的电动汽车无线充电系统中由于负载未知从而导致无法实现负载与功率相匹配的问题,提出一种基于S-LCL补偿拓扑的ICPT系统的负载识别方法,通过原边补偿电容两端电压与负载之间的关系确定负载的大小,同时该系统还能够在不加入任何控制的条件下实现负载的恒压输出,解决了传统方法造成的算法复杂、系统体积过大等问题。实验证明了基于S-LCL补偿拓扑的ICPT系统负载识别方法的有效性和实用性。

| Abstract: | In order to solve the problem that the load and power can not be matched because of the unknown of the loads in the wireless charging system of inductively coupled power transfer(ICPT)technology,a load recognition method for ICPT system based on S-LCL compensation topology was proposed.Through the relationship between the compensatory capacitor voltage and the load,the value of the load was determined.At the same time,the system could realize the constant-voltage output without any control,and solve the problem of the complexity of the algorithm and the large volume of the system caused by the traditional method.The experiment certifies that the load identification method of ICPT system based on S-LCL compensation topology is effective and practical. |
