摘　　要：分析同步Buck变换器工作模式,构造了非理想情况下Buck变换器的通用仿真模型,依据小信号模型,采用频域分析法设计了补偿网络,并在Matlab/GUI环境下开发了与Simulink交互的仿真系统调试平台。通过仿真实验,验证了通用模型的正确性,补偿网络设计的合理性。采用所设计的交互式仿真平台,有助于补偿网络参数的整定、仿真实验结果的对比,对于开发和研究Buck变换器有着十分重要的意义。The paper analyzes the operating mode of synchronous Buck converters, then constructs a general simulation model of Buck converters under non-ideal circumstances. According to the small-signal model, the compensation network is designed based on the frequency domain analysis method, and the simulation debug- ging platform which interacts with Simulink in Matlab/GUI environment is developed. The simulation results verify that the general model is effective, and the design of compensation network is reasonable. The paper maintains that the interactive simulation platform would help compensate network parameter setting and the comparison of simulation result is of great significance for the development and research of Buck converters.
