Sneak Circuit Path Analysis Method for Power Electronic Converters

Based on graph theory, this chapter introduces three sneak circuit path analysis methods by using adjacency matrix, connection matrix and switching Boolean matrix respectively, which can find all of the circuit paths existed in the power converter, and then identify the sneak circuit paths according to the operating principle of power converter. The proposed sneak circuit path analysis methods have been developed to the corresponding computer aided software, thereby the sneak circuit analysis of power converters can be realized automatically.
