Chaotification is an inverse problem of chaos control. This paper addresses the mechanism of chaotification of buck converter with time-delay feedback. The chaotification model is established moreover the article discusses the chaotification ruler of buck converter in a rigorous mathematic sense. The ranges of control parameters are given using nonlinear dynamics stability theory. Computer simulation...
Based on the analysis of constant frequency, periodical frequency-spreading scheme and chaotic frequency-spreading scheme, the article has discussed the mechanics and the characters of the chaotic PWM suppressing EMI in the converter. Experiments have been made on an AC-DC forward converter. The experiment results show that the EMI spectrum is decided completely by the PWM spectrum, and the chaotic...
