The invention relates to an inverter fault diagnosis method. The types of inverter faults comprise external wire loop short circuit, inverter main loop circuit, and inverter control loop abnormity. A D-S evidence theory recognition frame is built through the fault types, and fault symptoms of the inverter serve as the evidences for the D-S evidence theory recognition frame. Moreover, the method carries out the basic credibility distribution of each evidence. The method achieves the recognition of the fault types of the inerter through a D-S evidence theory integration rule and a decision rule. The method achieves the complete and detailed analysis and reasonable summarization of fault reasons of the inverter, and summarizes the fault reasons of the inverter. Therefore, an operator can carry out accurate maintenance according to a specific fault problem, and avoids a severe operation accident.
