Abstract
This paper presents an analytical model-based approach to detect and isolate faults in a voltage-source inverter. These faults do not affect the existing system protections. A diagnosis system which uses only the input variables of the drive is presented. It is based on the analysis of the current-vector trajectory in faulty mode. The proposed method has been verified in simulation results.
