Abstract
Power electronics converters have been widely used in aerospace system, DC transmission, distributed energy, smart grid and so forth, and their reliability has been a hot spot in academia and industry. It is of great significance to carry out power electronics converters open-circuit faults monitoring and intelligent fault diagnosis to avoid secondary faults, reduce time and cost of operation and maintenance, and improve the reliability of power electronics system. Firstly, the faults features of power electronic converters are analyzed and summarized. Secondly, some AI-based fault diagnosis methods and application examples with power electronics converters are reviewed, and a fault diagnosis method based on the combination of random forests and transient fault features is proposed for the three-phase power electronics converters. Finally, the future research challenges and directions of AI-based fault diagnosis methods are pointed out.
