提出了适用于电力电子变换器拓扑分析的广义连接矩阵，用于判别给定拓扑的电力电子变换器的开关路径，为分析变换器的开关模式提供了一种新的方法。同时，通过将变换器实际开关电路模态与电路设计的正常工作模态比较，可以判断变换器是否存在非设计要求的潜在开关路径，以便设计者及时对变换器的开关结构进行改进。最后，以三相PWM整流器和零电流谐振开关电容变换器为例，进行了详细的应用研究分析，验证实例证明了所提出方法是正确和有效的。

Based on a directed graph of power converters, a new generalized connection matrix method was proposed to find out all switch paths and states. By comparing practical switching states to normal states, the sneak circuit paths were identified accordingly. A new switch construction was developed to eliminate sneak circuits. At the same time, the method was used to analyze switching states of threephase PWM rectifiers and identify the sneak paths of zerocurrentswitching resonant switched capacitor (RSC) converters. The results show that the proposed analysis method is effective.
