摘　　要：针对平均电流控制的Boost PFC变换器存在动态性能不够理想等问题,基于平均电流控制的Boost PFC变换器,通过引入一个前馈补偿环节对传统平均电流控制进行优化。首先对平均电流控制的BoostPFC变换器进行了理论分析,并通过Simulink模块搭建了BoostPFC变换器电路模型,再搭建了平均电流控制和带前馈补偿环节的平均电流控制模型分别进行仿真,最后对仿真结果进行分析。通过仿真对比分析发现,在平均电流控制引入前馈控制方式后,提升了系统功率因数,提高系统响应能力和稳定性。In order to improve the dynamic performance of Boost PFC converter based on average current control,this paper introduces a feed forward compensation link to optimize the traditional average current control.Firstly,the Boost PFC converter with average current control is analyzed theoretically.The Boost PFC converter circuit model is built through Simulink module,and then the average current control model and the average current control model with feed forward compensation are simulated respectively.Finally,the simulation results are analyzed.Through the simulation and comparative analysis,it is found that the feed forward control mode is introduced into the average current control,which improves the system power factor and improves the system response ability and stability.
