| 摘 要： | BUCK开关转换器是一种典型的分段光滑动力学系统,改变转换器的电路参数条件会产生许多动力学行为。我们建立了电路的动力学方程,改变电路各参数,采用数值仿真的方法来分析了转换器的分岔和混沌现象。这对于研究其它DC-DC转换器具有一般意义。在这里采用的是MATLAB软件,并讨论了仿真时一些问题。

| Abstract: | BUCK converter is a kind of typical piecewise-smooth dynamical system. Changing the circuit parameter, much dynamical behavior can appear. The dynamical model of the circuit was constituted. The circuit parameter was changed, and the way of simulation was adopted to analyze the phenomenon of bifurcation and chaos of the converter. It is generally significant to study the other DC-DC converter. The MATLAB software, and a few problems were discussed during the simulation. |
