一种基于相似性的双脉冲整流器鲁棒开路故障诊断方法

This letter proposes a current similarity-based robust diagnosis scheme to detect open-circuit (OC) faults for insulated gate bipolar transistors (IGBTs) in dual pulse rectifiers. The similarity indicator between the ac-side currents of the two rectifiers is calculated based on the structural characteristics, which are independent of system parameters and naturally robust to voltage fluctuations a...
