摘　　要：为抑制Boost PFC变换器中的快时标分岔现象,采用频闪映射的方法对变换器建立数学模型,通过MATLAB/Simulink仿真软件绘制出电感电流的时域波形图和频闪采样图进行分析。施加谷值V2控制对变换器中的快时标分岔现象进行抑制,将传统斜坡补偿控制快时标分岔和谷值V2控制进行比较分析,仿真结果表明:在同等参数条件下谷值V2控制的控制效果较优于斜坡补偿控制,且谷值V2控制具有瞬态响应快、工程应用实现简单等优点。In order to curb fast-scale bifurcation in the Boost PFC converter,the strobe mapping method is used to build a mathematical model for the converter,and then the MATLAB/Simulink simulation software is employed to draw and analyze the time-domain waveform diagram and stroboscopic sampling diagram of the inductor current.Finally,valley value V2 control is adopted to curb fast-scale bifurcation in the converter.By comparing the curb effect of traditional slope compensation control with that of valley value V2 control,it is shown that valley value V2 control not only has better curb effect than slope compensation control under the same parameters,but also has the advantages of fast transient response and simple engineering application.
