Abstract

This paper presents a 6 kV motor drive consisting of a 24-pulse rectifier and a three-level neutral-point-clamped (NPC) inverter using IGCTs. It is suitable for feeding standard industrial motors. Experimental results from the industrial installation show that the design and the implementation are successful.
