摘要 DC-DC变换器中存在着丰富的非线性现象,分岔的出现是DC-DC变换器失稳的表现。为研究DC-DC变换器中的分岔现象,采用采样数据法建立DC-DC变换器的精确数学模型,给出对分岔现象进行仿真分析的公式,以Buck变换器为例,通过仿真和实验观察不同参数下分岔现象的出现,从而得出电路参数变化对DC-DC变换器稳定性的影响。 There are kinds of nonlinear phenomena in DC-DC converters, and the appearance of bifurcation implies that the DC-DC converter is unstable. To study the bifurcation phenomena, a precise sampled-data model for DC-DC converters was set up in the first step, then formulae for bifurcation simulation were derived, at last, a buck converter was studied as an example. Observing bifurcation phenomena under different circuit parameters in simulation and experiment will help us to determine the stable values.
