摘　　要：为了深入研究具有斜坡补偿的Buck-Boost变换器的碰撞分岔现象及混沌,导出了电流模式控制Buck-Boost变换器运行轨道转移时的两个边界方程,从而建立了具有两个边界的三段光滑非线性离散迭代二维映射方程,并通过数值仿真得到了输入电压、斜坡补偿电流的斜率和负载电阻R变化时的动力学行为分布图.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.

关 键 词：BUCK-BOOST变换器 斜坡补偿 迭代映射方程 边界方程
