New Method of Wavelet and Support Vector Machine for Power Electronic Fault Diagnose

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.
