Study of Bifurcation and Chaos in the Current-Mode Controlled Buck-Boost DC-DC Converter ( Ⅱ ) --Numerical Analysis and Experiment |
| |
Abstract: | The first flip bifurcation point of Buck-Boost converter has been studied in detail by using fixed point and stability theory. 3-D parameter space of stable region is given. Furthermore, the hardware of 20kHz current-moxe controlled BuckBoost converter has been built and the experiment results verify the theoretical analysis which has been presented in our other papers. |
