摘　　要：为解决非接触电能传输系统中负载电阻变化会导致系统传输能力变化的问题,研究非接触电能传输系统在并联—串联拓扑下负载变化时无功功率的补偿问题.通过分析理想可变初级电容的可控性,提出用积分控制器对可控电抗器进行动态调节以完成负载变化时的无功功率补偿.数值仿真表明,该控制方案是可行的.In order to solve the problem that variations of a load resistance generally lead to a change of the system power transfer capability,the reactive power compensation mechanisms are investigated for contactless power transfer systems with a variable load under a topology of parallel compensated primary and series compensated secondary.Based on the controllability analysis of an ideal variable primary capacitance,a method of reactive power compensation under a variable load is propsed by using an integral controller to regulate a variable inductor dynamically.Numerical simulations indicate that the control strategy is feasible.
