Fault detection and localization for T-Type Converter
Résumé
In this paper, an Open-circuit switch fault diagnosis method for a five-level H-Bridge T-type converter is presented. The proposed fault detection method and the fault localization algorithm are based on the switching patterns and the converter output voltage level observation. The proposed fault diagnosis approach is capable to detect and localize an open circuit fault for all switches. The proposed approach is validated by simulations in Matlab Simulink and SimPowerSystem toolbox environments.
