摘要
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。
Based on neural network theory,a new on line fault diagnosis method for power electronic circuits is presented.A neural BP network is founded,which is able to diagnosis faults of three phase rectifier effectively.The method is verified by both simulation and experiment.
