Research on Intelligent Fault Diagnosis Technology of Power Electronic Circuits

Electronic products are an important measure of a country’s technological level. In recent years, China’s science and technology have developed rapidly, but under the technological innovation of electronic products, many power electronic circuits have failed and the impact is extremely serious. This article summarizes the common fault diagnosis methods of power electronic circuits based on previous work experience. The author discusses the specific application of intelligent fault diagnosis technology for power electronic circuits from four aspects: establishing a complete data information database, detecting multiple transmission line faults, accurately simulating circuit operation, and main circuit fault diagnosis.
