摘　　要：建立了电力电子变换器潜电路的邻接矩阵分析方法。将变换器各元件间的连接状态采用邻接矩阵存储,通过深度优先搜索算法对邻接矩阵中处于连接状态的顶点序列进行搜索,根据路径判别条件实现了潜电路的识别,得到用顶点序列描述的潜电路路径。以C和VC++6.0为平台编制了基于邻接矩阵的电力电子变换器潜电路分析软件,并以升压谐振开关电容变换器潜电路的分析为例,详细分析了算法的实现过程,验证了算法的有效性。Sneak circuit analysis method based on adjacency matrix for power electronic converters was proposed.The connection status between different terminal vertex in the converter was stored in an adjacency matrix.All vertex sequences in connecting status were found by the depth-first search algorithm.It was found that the sneak circuits marked by vertex sequence can be identified through some path criteria.Sneak circuit analysis（SCA） program based on adjacency matrix was designed in C and C＋＋6.0.The performance of a sneak circuit analysis on a step-up resonant switched capacitor converter demonstrated the validity of the proposed SCA program.
