| 摘 要： | Buck-Boost电路中含有丰富的非线性现象。它工作过程中电路拓扑结构的循环切换导致了谐波、分叉和混沌等非线性行为。基于PSPICE仿真,研究了电流控制DC/DC Buck-Boost开关转换器中的倍周期现象。而且,建立了开关转换器的数学模型和叠代映射来解释这种非线性现象。基于MATLAB仿真,从叠代映射中得到了系统分叉图。

| Abstract: | A buck-boost circuit is rich in nonlinear dynamics. Its operation is characterized by cyclic switching of circuit topologies, which gives rise to a variety of nonlinear, such as subharmonics, bifurcation and chaos. Based on PSPICE, the period-doubling phenomena exhibited by a current-programmed DC/DC buck-boost switching converter are studied. Furthermore, the system model and the iterative map of the converter are derived to explain the nonlinear phenomena. Based on MATLAB, the numerical simulation with this iterative map has led to the bifurcation diagram. |
