| Abstract: | In this paper, the reasons and the types of fault occurred in power electronic circuits are discussed. Combined with fractal, the characteristics of output voltage are extracted based on the fractal dimension. A news fault diagnosis method is given. In three-phase rectifier circle, the relationship between the fractal dimensions of the output voltage and the faults are set up, the fault diagnosis of circuits is achieved. |
