IHBA-optimized DR-SE-NPCNet for robust open-circuit fault diagnosis in three-level NPC inverters under mixed and noisy conditions

Abstract Open-circuit faults (OCFs) in three-level neutral-point-clamped (NPC) inverters can severely degrade power quality and compromise system reliability. However, existing diagnostic methods often exhibit performance degradation under mixed operating conditions and strong noise, and they remain...
