A Dual-Stream Network with Dynamic Graph Convolution and Attention-Based BiGRU for IGBT Open-Circuit Fault Diagnosis in T-NPC Three-Level Inverters
Existing CNN, TCN, residual, and lightweight network methods have achieved good performance in IGBT open-circuit fault diagnosis, but they often overlook the non-Euclidean relationships among signals. To address this limitation, this paper proposes a parallel graph–temporal network for T-NPC three-level inverters. A sh...
