摘要：
Based on support vector machines (SVM) theory, a new method of fault diagnosis for controlled rectifier circuits is proposed in this paper. Fault diagnose method of power electronic converter has been studied on the basis of direct waveform analysis and SVM. Three-phase bridge rectifier circuit fault is presented as an example, coupled with the results of a certain power electronic circuit experiment, indicates that the method can accurately diagnose and locate fault for controlled rectifier circuits, which is justified practical and applicable for controlled rectifier circuit fault diagnosis.
