摘要
推导了电流模式Buck-Boost变换器的迭代映射模型,在该模型的基础上研究了以输入电压、参考电流和负载电阻为电路变化参数的分岔现象.利用Matlab仿真得到分岔图,从图中可以得知分岔变量可能影响到系统的状态,在设计中可以利用此规律选择最优参数.
The iterative mapping model of current-mode Buck-Boost converter was deduced. On the basis of the model, bifurcation phenomena were studied with input voltage, reference current and load resistance as variable parameters. Bifurcation diagrams were obtained by Matlab simulation, and it can be seen from the figures the effects of bifurcation parameters on system states. In designs,optimal parameters may be chosen in the light of the rules summarized in the paper.
