Abstract:

Aircraft starter/generator, meeting the lightweight and high integration requirements of more electric aircraft for aircraft power supply system, has been widely studied. Fault diagnosis of its components is crucial to ensuring the safe, stable and efficient operation of aircraft power supply system. As the most prone component to failure, rotating rectifier’s fault diagnosis is of great practical significance. This paper systematically reviews current researches on rotating rectifier fault diagnosis methods. Firstly, the development status is summarized both domestically and internationally from four perspectives: fault modeling, fault signal processing, intelligent algorithm application and industrial fault detection technology. Secondly, the common diode faults and fault transfer path in rotating rectifier are introduced, along with some difficult points of fault diagnosis in practice. Then, analyzing fault mechanism and starting from the different ways to acquire fault electrical signal, existing fault diagnosis methods of rotating rectifier are classified and summarized. Their advantages, disadvantages and application scope are discussed in depth. Finally, a comprehensive outlook on the future development trends of rotating rectifier fault diagnosis is provided to offer insights and references for colleagues interested in this field.
