Mixed cells modular multilevel converter [PDF]
This paper uses a scaled down version of the mixed cells modular multilevel converter (MMC) to discuss its modulation and capacitor voltage balancing method, and investigates its AC and DC fault ride-through capability. It has been found that the mixed MMC is resilient to both AC and DC network faults, which are necessary for next generations of highly

AC–AC Modular Multilevel Converter—Hexverter
This article proposes the study, control and analysis of the topology of an AC–AC modular multilevel converter, known in the literature as the Hexverter. The Hexverter is capable of converting the energy between two AC systems with a reduced number of elements, if compared with other modular multilevel topologies, which makes this topology attractive ...
