Abstract :
This paper presents the results of an implemented control strategy applied to an IGBT based Medium Voltage inverter with NPC topology driving a salient-pole synchronous AC machine. Tests with a 1000 HP synchronous machine and a three level inverter (4.16 KV / 120 A) were performed. The control system provides a high dynamic performance with a fast torque control. The additional functionalities necessary to drive a synchronous AC machine are depicted. The results also show the behavior of a synchronous bypass transfer of the machine from the inverter to the line supply.
