Open-Switch Fault Diagnosis for Grid-Tied HANPC Converters Using Generalized Voltage Residuals Model and Current Polarity in Flexible Distribution Networks

Open-Switch Fault Diagnosis for Grid-Tied HANPC Converters Using Generalized Voltage Residuals Model and Current Polarity in Flexible Distribution Networks

The diagnosis of open-circuit (OC) faults in power switches is the premise for implementing fault-tolerant control, a critical aspect in ensuring the reliable operation of three-level hybrid active neutral-point-clamped (HANPC) converters in flexible distribution networks. However, existing fault di...
