Abstract :
This paper introduces a new approach, based on the average motor supply current Park´s vector monitoring, for diagnosing voltage source inverter faults in variable speed AC drives. Both simulation and laboratory tests results demonstrate the effectiveness of the proposed on-line diagnostic technique
