| 摘 要： | 研究了电流控制型Buck-Boost变换器中的分叉与混沌问题. 首先, 对连续模式下的Buck-Boost变换器建立了离散数学模型, 在此基础上, 在输入电压E、参考电流Iref、电阻R、电感L和电容C等分叉参数作用下, 通过数值方法对Buck-Boost变换器中的分叉与混沌进行了详细的仿真研究. 仿真研究结果表明: Buck-Boost变换器具有丰富的非线性行为———分叉与混沌, 随着各个分叉参数的变化系统会遵循倍周期分叉的规律走向混沌.

| Abstract: | This paper studies the bifurcation and chaos in current-mode controlled Buck_Boost converter. The discrete model for Buck-Boost converter in continuous conduction mode (CCM) is derived. The bifurcation and chaos phenomena of Buck_Boost converter have been investigated with input voltage E, reference current I ref,resistor R, inductor L and capacitor C as bifurcation parameters. |
