一种基于归一化直流电流的感应电机驱动系统匝间短路与开路故障统一诊断方案

This article provides a novel real-time fault diagnosis unified approach of stator interturn short circuit faults (ISCFs) and open-switch faults (OSFs) in voltage source inverter-fed three-phase induction motor drive systems without requiring additional hardware even for ISCFs involving fewer turns. The proposed diagnosis approach leverages the normalized dc components of stator line currents and ...
