将脆弱性分析引入到电力电子变换器结构性故障的研究,具体研究方法是基于信息化学中拓扑指数的概念,计算出Buck变换器的拓扑指数,提出Buck变换器脆弱性判定方法。通过对Buck变换器拓扑指数的计算和分析,量化不同故障对Buck变换器运行特性的影响。脆弱性的研究将为电力电子变换器安全稳定运行和故障诊断提供一个新的分析思路。

The vulnerability analysis of structural faults of power electronic converters was firstly introduced, which could calculate the topological indices of buck converter based on the topology index theory applied in information chemistry. The buck converter was analyzed and the topological indices are calculated and analyzed to find out the impacts of different faults on their operation characteristics, then their topological vulnerability can be showed finally. The method will give a novel way for research on the stable operation and fault diagnosis in power electronic converters.
