Survey on the Hexverter topology — A modular multilevel AC/AC converter

The Hexverter modular multilevel converter topology has been recently proposed for three-phase to three-phase AC/AC conversion. This paper outlines the current state of the art of the Hexverter. The basic working principle is explained and the control concept is introduced. The differences to alternative topologies are discussed and possible applications are pointed out.
