Feature information extraction, which directly influences the validity of diagnosis result, is an important link in power electronic circuit fault diagnosis. This paper summarized some methods of fault feature extraction in common use and evaluated the advantages and disad-vantages of each method with the combination of practical application. On the basis of this, this paper proposed a new idea for future feature ex-traction methods, which constructed the feature extraction method to bring each advantage into play and to realize the complementary function, to provide reference for further improving the accuracy of fault diagnosis.
