A New Fault Diagnosis Method for Power Electronic Circuits──Walsh Transform Method

Xu Dehong; Chang Zhaoji; Fan Yunqi(Zhejiang University)  
A new on-line fault diagnosis method for POwer electronic(PE) circuits is presented. Since signals of key points in PE circuits, which include fault information,are generally periodical, they are able to be transformed with Walsh Transform.In the Walsh transform field, feature vectors are found, which are able to isolatedifferent faults effectively.
