Abstract :
This paper evaluates three-level topologies as alternative to two-level topologies in converters for low voltage applications. Topologies, semiconductor losses, filter aspects, part count, initial cost and cost over life-cycle are compared for a grid interface, a conventional drive application, and a high speed drive application.
