The Simulation and Research of Chaos in Current-Controlled Boost DC / DC Converter
For the non-linear phenomena of the switching power supply, the discrete mathematical model of current-controlled Boost DC/DC converter has been presented in this paper, according to the switch maps. The results of simulation and experiment are derived, and the variable is the current of inductor. The accuracy of the model has been verified by the results of simulation and experiment which reveales the DC / DC converters from the bifurcation and eventually to the phenomenon of chaos. The theoretical basis using or avoiding chaos is provided for the power supply design.
