Intergovernmental Science and Technology Innovation Cooperation Special Project of National Key R&D Program of China under 2016YFE0132300.To reduce the negative impacts of power converters on a machine such as switched reluctance motor (SRM) a fast and accurate fault detection method is required. Several fault types could occur in SRM drives, such as, open and short-circuit transistor faults. Thus, this paper presents a new fault detection and diagnosis method for transistor faults in a SRM drive. The method is based on symmetry indexes that are created from the analysis of the currents patterns. The proposed approach results in a fast and robust method, presenting immunity to different mechanical conditions. The characteristics of the proposed method will be verified through several simulation tests.759878engfault detectionopen switchswitched reluctance motor (SRM)symmetry indexesElectrical and Electronic Engineeringconference object10.1109/BEC.2018.8600966https://www.scopus.com/pages/publications/85061479720
