| Abstract: | Based on artificial neural network theory, a new fault diagnosis method for power electronic circuits is presented. A neural BP network is founded, which is able to diagnosis faults of three-phase rectifier effectively. Number of laysers and nodes of the neural BP network is designed. The sample data is acquired by setting up the model of three-phase rectifier circuits, and the artificaial neural network is trained.The simulation results show that the method of the neural BP network with four layers diagnosing three-phase rectifier circuits is correct. |
