| Abstract: | A fault diagnosis system for power electronic rectifiers based on virtual instrument was described.The data of three-phase rectifier circuit were collected.By the virtual instrument technique integrated with the neural-network system,real time analysis of the data was performed with the dia-gnostic result being output immediately.The simulation result indicates that the fault diagnosis method is valid and feasible. |
