DC-DC变换器中的分岔现象综述

Bifurcation phenomena in DC-DC converters

介绍了分岔理论的发展历程,概述了分岔现象在DC-DC变换器中的研究状况,较为详细地介绍了静态分岔和动态分岔的基本理论以及常用的三种建模方法:状态空间平均法、频闪映射法和采样数据法,其中采样数据法是一种系统而准确的方法.最后,通过对一个buck变换器的仿真和实验研究说明了建模方法的有效性.

The development of bifurcation is reviewed mad the research status of bifurcation phenomena in DC - DC converter is summarized. The paper also introduces the basic theory of static bifurcation and dynamic bifurcation and three modeling methods in common use： the state-space average method, the frequency mapping method and the sampled-data method. The sampled-data method is more systematic and more accurate than the others. Finally, the simulation and experiment of an example explain the validity of the above modeling methods.
