| Abstract: | In order to research the collision bifurcations and chaos in Buck-Boost converter with ramp compensation,two borderline equations of the orbit states shifting in current-mode controlled Buck-Boost are deduced in this paper,thus 3-piece smooth nonlinear discrete 2-dimension iterative maps with two borderlines are established,and the dynamic behavior distributions with the variations of input voltage,slope of compensation current and load resistance R are obtained by simulations. |
