摘      要：For diagnosing failure and sick rectifying elements, a fault detection and prediction method of rectifier was presented in this paper. The output voltage of rectifier was contrasted with normal simulation signal in phase to obtain the difference signal. After it was processed according to the set threshold, the coding of the difference signal was achieved. The signal coding was adopted to diagnose failure elements or sick elements. In simulation test, the fault code tables of rectifier with different control angle were given. The simulation results show the validity of the fault detection method presented in this paper.
