It is difficult to describe and verify precisely the bifurcation and chaotic phenomena of DC/DC converters by the mathematic models and experiments. This paper develops a method for establishing the precise discrete model of bifurcation and chaos in Buck DC/DC converter, and obtains its precise discrete mathematic model. Based on the model, Chaotic characteristics and bifurcation stability of Buck DC/DC converter are analyzed. On the other hand, this paper carries out rich experimental researches, which verify the precise discrete model to be accurate, and show the process from bifurcation to chaos of Buck DC/DC converter. Otherwise the research methods provide the theoretical and experimental basics for analyzing the bifurcation and chaos in other DC/DC converters.
