Abstract :
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 illustrates the validity of the proposed method, and depicts the influence of different control parameters. At last experiments are done; theoretical results are verified by experimental measurements.
