摘　　要：研究了松耦合全桥谐振变换器的闭环控制,以初、次级均采用串联补偿为例进行分析,得出了该补偿方式的一些特性;分析了在该补偿方式下,使用脉冲频率调制(Pulse Frequency Modulation,简称PFM)方式进行控制时,系统工作频率范围的选取;设计了基于UC3861控制的实验样机,并进行了实验验证。Closed-loop control of the loosely coupled inductive power transfer full-bridge resonant converter was studied.The characterisfies of the compensation were obtained taking the situation that primary and secondary compensation were series for example.How to choose the switch frequency by pulse frequency modulation（PFM） was analyzed.The experimental results from a prototype of full-bridge converter based on UC3861 control are given ,which verify the correctness of analysis and conclusion.
