| Outline of Final Research Achievements |
Application of the hierarchical control system to the Modular Multilevel Matrix Converter (MMMxC) that is a member of Modular Multilevel Converter (MMC) family is investigated. The hierarchical control system enables 1)flexibility in the increase of the number of cells, 2)simplification of power control, zero sequence voltage suppression control and capacitor voltage balancing control, 3)improvement of Fault Ride-Through (FRT) capability against a voltage sag and voltage/current unbalance. In this research, these features were demonstrated through numerical simulation and experiments using a 2-kVA 7-level small-scale MMMxC. These results indicate that the MMMxC with the hierarchical control system is one of the promising high-capacity high-voltage frequency converters.
