Abstract:

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 for using neural network to watch and control DC-DC converter intelligently.
