中文摘要:
      电压控制型Buck变换器是典型的非线性电路系统。根据DC-DC Buck变换器的工作特性,建立了研究其非线性现象的仿真模型,分析了Buck变换器的分岔稳定性和混沌化特性,揭示了以输入电压和电感作为分叉参数的混沌现象及系统输出特性;从时域角度分析参考电压波形与输出电压波形交点的变化对变换器工作状态的影响,在相图中得到系统由稳定到混沌的演化过程,并验证了该模型的合理性和可行性。该研究方法也为其他模式DC-DC变换器的分岔与混沌现象提供理论和实验基础。
英文摘要:
      The voltage-controlled Buck converter is a typical nonlinear circuit system. According to the working characteristics of the DC-DC Buck converter, a simulation model for studying its nonlinear phenomena is established. The bifurcation stability and chaos of the Buck converter are analyzed. The chaotic phenomenon and system output characteristics are revealed by taking input voltage and inductance as bifurcation parameters. The influence of the intersection point of reference voltage waveform and output voltage waveform on the operating state of the converter is analyzed from the perspective of time domain. The evolution process of the system from stability to chaos is obtained in the phase diagram. The rationality and feasibility of the model are verified. The research method also provides theoretical and experimental basis for the bifurcation and chaos of converters with other modes of DC-DC.
