This paper describes a novel approach to the detection and localization of semiconductor faults in VSI-fed AC drives. We use the DC-to-fundamental motor current ratio as the diagnostic variable. The method has proved to reliably detect true faults, while not issuing false alarms under transient conditions. The method has been validated by both simulation and experiment.
