| 摘 要： | 对于功率电子中混沌问题的研究结果表明，人们不仅可以驾驭混沌，而且还可以利用混沌。该文对Ｌｏｒｅｎｚ混沌系统进行分析，从中阐述了混沌的基本理论。以降压式ＤＣ－ＤＣ变换器为例，对功率电子电路中的混沌现象进行了探讨，并通过计算机仿真观察到了功率变换器随着输入电压Ｖ１的变化而呈现出的混沌波形。文中的波形都是利用ＭＡＴＬＡＢ软件通过计算机仿真获得的，便于读者自行验证。

| Abstract: | The research on chaos in power electronics showns that chaos can be not only controlled but also utilized in many areas.In this paper Lorenz chaotic system is analyzed so as to describe the chaos basic theory. In terms of the example of a PWM controlled buck dc dc converter, one of the power electronics circuits, chaotic waves are observed numerically with the variation of input voltage. All waves are obtained by MATLAB simulation software so that those can be verified by readers themselves. |
