| 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。 |
| 关 键 词： | 分岔 DC-DC变换器 采样数据模型 仿真 |

| Abstract: | 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. |
| Keywords: | bifurcation DC-DC converter sampled-data model simulation |
