摘要
The precondition of realizing feedback controlling DC DC converter to avoid chaotic state is to judge the behavior of the converter and take corresponding measures. In this paper, the output signals under different circuit parameters of the PWM buck converter have been analyzed. The method of using Fourier descriptor to extract output signals characteristics is put forward and proved to be a gist of identifying and classifying the behavior of DC DC converter. This method can establish a good foundation fo...
实现对DC DC变换器进行有效的反馈控制避免进入混沌态的前提是能根据变换器输出信号的特性 ,对变换器的工作行为作出正确的判断并采取相应的控制措施 .本文以PWM型BUCK变换器为研究对象对其在不同电路参数下的输出信号进行了分析研究 ,提出并证明了用傅里叶描述符法提取输出信号的特征值可以作为判断变换器工作行为的依据 .
