摘要
基于Simulink建立了电流连续导通模式下的电压控制Buck变换器模型,在该模型的基础上对开关变换器的非线性现象进行了研究。通过改变电路参数,研究了开关变换器从稳定态到倍周期分岔,再到混沌的演化过程。仿真结果与理论分析和实验结果一致,验证了仿真模型的正确性,为合理选取电路参数提供了指导,同时也为混沌控制理论的研究奠定了仿真基础。
A model of voltage control Buck converter operating in continuous current mode is established through Simulink.The nonlinear dynamics phenomenon in converter is studied according to the model.By changing the circuit parameters,the transformation of converter from steady state to bifurcate and then to chaotic is investigated.The simulation results are consistent with theoretical analysis and experimental results,thus confirming the correctness of the model.The proposed model may be a useful reference for parameter selection and a preliminary foundation for theoretical study of chaos control in Buck converter.
