【摘要】 文章首先利用分叉理论分析了分叉现象发生的条件,然后介绍了用来分析电力电子中非线性现象的数据采样模型(Sample-data Model)技术。最后以Buck变换器为例,说明了在电力电子领域中存在的两种常见的分叉现象,并利用数据采样模型技术分析了产生这些分叉的条件。更多还原

【Abstract】 In this paper the condition when bifurcation phenomena occur is analyzed with bifurcation theory, and a technique named the Sampled-Data model, which is applied to analyzing the nonlinear phenomena in power electronics, is introduced. Taking Buck converter as an example, two bifurcation phenomena in power electronics are showed and the condition when these bifurcations occur is analyzed with the Sampled-Data model technique.更多还原
