Control of a Modular-Concatenated-Cell (MCC) Multilevel Converter Topology Exploiting Logic-Equations Method

A modular-concatenated-cell (MCC) multilevel voltage-source converter topology is investigated in this paper, and its basic configurations are reviewed. A set of logic-equations are derived for control of the 1-cell 3-level and 4-cell 6-level MCC inverter topologies. Simulation results are provided to confirm the four-cell 6-level configuration and the proposed logic-equations. Furthermore, a 3-level MCC converter topology and its logic-equations-based modulation technique are experimentally verified using a 2 kW laboratory prototype.
