The Development Research of Plug and Play Rectifier Fault Diagnosis Device

Abstract

Based on support vector machines (SVM) theory, the method of fault diagnosis for controlled rectifier circuits is expanded to study in the paper, by the basis we analysis the method can be applied to diode rectifier circuit and verified it through the experiment. In addition to this , the rectifier circuit with different types of loads are also simulated to describe the reason this method is applicable to the different types of loads. In the premise of ensuring the accuracy of the method, through the expansion of research, the fault diagnosis method has broader prospects and higher practical value.
