摘要
本文提出了一种电力电子电路故障在线诊断方法。电力电子电路中包含故障信息的关键点波形,通常具有周期性,采用沃尔什变换将时域中的关键点波形的一个周期变换到列率域中,利用本文提出的列率域中的一套故障特征,能够有效地实现故障的定位。
A new on-line fault diagnosis method for POwer electronic(PE) circuits is presented. Since signals of key points in PE circuits, which include fault information,are generally periodical, they are able to be transformed with Walsh Transform.In the Walsh transform field, feature vectors are found, which are able to isolatedifferent faults effectively.
