Fault Diagnosis Method for Open-circuit Faults in NPC Three-level Inverter based on WKCNN

Fault Diagnosis Method for Open-circuit Faults in NPC Three-level Inverter based on WKCNN

With the increasing demand for high reliability and availability in power conversion equipment within power electronics systems, the fault diagnosis of neutral-point-clamped (NPC) three-level inverters has garnered widespread attention. To address the challenges of fault feature extraction, this art...
