摘　　要：针对传统感应耦合电能传输(ICPT)系统功率因数低下问题,以推挽式ICPT系统为研究对象,结合有源功率因数校正(PFC)技术,对系统功率因数进行研究。本文中有源功率因数校正电路采用基于平均电流模式的Boost电路,并且对推挽式ICPT系统进行等效阻抗分析。在此基础上,针对系统中Boost电路中电感电流过零点存在畸变现象,研究电流环的重复控制策略。最后,利用Matlab软件搭建了仿真平台,对系统进行仿真,验证了理论分析的正确性。Aiming at solving the low power factor problem of traditional inductive coupled power transfer （ICPT） system, the power factor of push-pull ICPT system was researched combined with the active power factor correction （PFC） technology. In the paper, the average current-mode boost circuit was used in the active power factor correction circuit, and the equivalent impedance in the push-pull ICPT system was analyzed. Then, on this basis, the repetitive control strategy of current loop was studied for the distortion phenomenon existing in the zero-crossing point of the inductance of the boost circuit. Finally, the simulation plat- form of the system was constructed by using Matlab, and the validity of theoretical analysis was verified by the results of simulatlon.
