提出采用基于波形直接分析的神经网络故障诊断方法实现电力电子电路在线故障诊断，以三相整流电路为例，选用ＢＰ网络对其进行了有效故障诊断。仿真和实验表明，其方法是有效的。
A fault diagnosis method of neural network based on waveform direct analysis is proposed to realize the on-line fault diagnosis of power electronic circuit. Taking the three-phase rectifier circuit as an example, BP network is selected to conduct effective fault diagnosis. Simulation and experiment show that the method is effective.
