    Fault Diagnosis of Power Electronic Circuits Based on Wavelet Multi-resolution Analysis and PCA

      Graphical Abstract
      • Abstract
    • Wavelet multi-resolution analysis method,principal component analysis method and induction-based learning theory-decision tree method,are applied to diagnose faults of power electronic circuits.Diagnostic efficiency and classification rate are both improved.Satisfied simulation results are obtained.
