摘要：

Diagnosis and location of the power transistor open switch and short circuit switch faults in inverter are studied. Wavelet transform is used to extract diagnostic indices from the current, speed and torque waveforms of brushless DC drive system. RBF neural network is developed to identify and locate the fault. RBF neural networks are trained offline using simulation results under various healthy and faulty conditions from a simulation model. Simulation results confirm the effectiveness of the proposed methodology.
