基于续电流的功率变换器故障诊断方案
A Study of Fault Diagnosis of Power Converter Based on Stream Current
摘要
Abstract
Aimed at the four typical electrical troubles of power converter in the switched reluctance start-ing/generation system,and on the basis of analyzing upper and lower following current,and introduction of digitizer ,a new method of fault diagnosis is proposed.Converter's operational principle and the energy con-vent process are analyzed.The effects of faults on the upper and lower following current are analyzed in ex-citing state and current�following state,then,according to the fault�feature,the scheme of fault diagnosis is put forward based on the difference between upper and lower following current.Finally,a fault diagnose model of switched reluctance starter/generator is built and validated.The result shows that the fault diag-nosis scheme is more accurate than that of the fault diagnosis with only phase�current.关键词
