The combination of wavelet and support vector machine was introduced to solve automatic detection of power electronic fault diagnose.Wavelet analysis which holds multi-resolution and multi-scale was introduced to deal with the signal characteristics.Support vector machine could carry through the pattern recognition on the small-samples and had well generalized ability.Based on wavelet analysis for signal characteristics,the distributed multi-SVM classifier was utilized to identify the power electronic fault diagnose,the experimental results also show that this method can efficiently identify and diagnose the power electronic fault diagnose.
