AC–AC Modular Multilevel Converter—Hexverter

This article proposes the study, control and analysis of topology an AC–AC modular multilevel converter, known in literature as Hexverter. The Hexverter is capable converting energy between two AC systems with a reduced number elements, if compared other topologies, which makes this attractive applications. However, there are few studies about literature, so work presents its operation principle, conducts modeling, scheme for converter’s proper operation, validating via hardware-in-the-loop emulation.
