Abstract :
A method of fault diagnosis for power electronics rectifier based on PCA-SVM is adopted in this paper. First, the features of the fault was extracted by the method of principal component analysis (PCA), and an SVM algorithm was introduced to train the SVM for diagnosis. Experimental results show that the diagnostic method has very good diagnostic ability and efficiency, and have a good outreach capacity under small-sample. Thus, it has very good practical value and applicable prospect in the solution to fault question for power electronics rectifier.
