摘要
提出采用神经网络和频谱分析实现电力电子电路在线故障诊断的方法，以三相整流电路为例，对其故障情况进行了分析，并选用ＢＰ网络进行了有效的故障诊断． 仿真和实验表明，本方法是有效的．
Based on neural network theory and frequency analysis,a new on\|line fault diagnosis method for power electronic circuits is presented. A neural network is developed,which is able to diagnosis faults of three\|phase rectifier effectively. The method is verified by both simulation and experiment.
