两种基于神经网络的电力电子电路故障诊断方法比较

Two Fault Diagnosis Methods Comparison of Power Electronic Circuits B ased on Neural Network

对两种基于神经网络的电力电子电路故障诊断方法：基于波形直接分析的方法和基于频谱分析的方法，进行了进一步地分析比较，并以三相整流电路为例。

Comparison of two fault diagnosis methods of power electronic circ uits based on neural network is presented. In one method, signals are analyzed d irectly by neural network. In another method, frequency analysis is performed be fore neural network analysis. Fault diagnosis of three-phase rectifier is presen ted as a example.
