Open-circuit diagnosis method based on dual-mode voltage residual model for T-type three-level inverter

Abstract This study proposes a rapid online diagnostic method based on a dual-mode line voltage residual model for diagnosing IGBT open-circuit faults in a T-type three-level inverter. The method is based on the voltage residual method and is integrated with a three-level fault-tolerant algorithm. F...
