| 摘 要： | 为解决Buck变换器混沌现象影响输出轨迹的问题,分析了变换器从稳定到倍周期分叉及混沌的原因,提出了混沌控制Buck变换器输出的新方法。仿真表明:变换器输出电压与电路参数和初始状态存在密切关系,当L1为1 mH、V1为37 V时,变换器出现倍周期分叉;当L1为3 mH、V1为35 V时,变换器出现混沌。该研究结论揭示了变换器出现混沌的原因和规律,可为工程设计人员的变换器电路参数优化设计提供参考。

| Abstract: | In order to solve the problem that chaos phenomenon affects the output result in Buck converter,the reason causing the circuit to be period-doubling bifurcation and chaotic from stabilization has been analyzed and a new method for controlling the chaos of Buck converter outputs has been proposed.The simulation shows that the output voltage of the converter has close relation to the circuit parameter and initial states.The phenomenon of period-doubling bifurcations appears in converter when L1 is 1 mH and V1... |
