Novel Distributed Control Platform and Algorithm for a Modular Multilevel Matrix Converter
The modular multilevel matrix converter (M3C) is an attractive topology for low-speed drives and doubly fed induction generator applications. Both modularity and scalability make the topology attractive for high-power medium-voltage systems.

Hybrid control approach for fast switching MMCs
This study presents a new hybrid control approach for different control and switching frequencies for converters of the modular multi‐level converter (MMC) family. Using this concept, it is possible to achieve a higher switching frequency and output voltage update frequency than the MMC control frequency.
