基于关键区域共性特征的逆变器开路故障诊断方法

Open-circuit fault of power switch is one of the common fault types in motor drive system. Diagnosing open-circuit fault accurately and quickly is very important. The regulation by controller often impairs the regularity of faulty current characteristics. The multipossibility of the control parameters will weaken the generalization ability for some fault diagnosis methods, which means that the acc...
