介绍了平均电流控制型 PFC Boost 变换器的结构， 分析了其工作原理。 分别采用 Power System 工具箱和考虑电感电流断续工作状态的 C-MEX 文件 S 函数建立了主电路模型，对平均电 流控制型 PFC Boost 变换器进行了仿真。仿真结果表明，与 Power System 工具箱模型相比，基于 C-MEX 文件的 S 函数仿真模型能够准确仿真电流断续工作状态，仿真速度快。设计了电路样机进 行了实验研究，仿真结果与实验结果一致，证明了该方法的正确性。利用该方法可以高效地仿真 研究系统结构和参数变化时性能变化情况，得到的平均电流控制型 PFC Boost 变换器的混沌分岔 图，为更好地理解和设计这种变换器提供了有利的工具。(The structure of average current controlled power factor correction (PFC) Boost converter is introduced, and its working principle is analyzed. The PFC Boost converter is simulated using the model established with Power System toolbox and the C-MEX file S-function model respectively. Simulation results show that the C-MEX file S-function model can simulate the all state of the converter including discontinuous conduction mode with high speed. Experimental results show the correctness of the simulation results and the proposed method. The method is suitable for simulation the performance changing with the variation of system structure or parameters. The bifurcation diagram is derived for PFC Boost converter using this method, which is very useful for better understanding and better design of the converter.)
