The research on chaos in power electronics shows that people can not only control chaos, but also make use of chaos. This paper analyzes the Lorenz chaotic system, and expounds the basic theory of chaos. Taking the step-down DC-DC converter as an example, the chaos phenomenon in the power electronic circuit is discussed. The chaos waveform of the power converter with the input voltage VI is observed by computer simulation. The waveforms in the text are all obtained by computer simulation through MATLAB software, which is convenient for readers to verify by themselves.
