Abstract

Cascaded H-bridge multilevel converter (CHB) is a promising topology for grid-connection systems. On the other side, model predictive controls are advanced control strategies which have many advantages for power converters applications like as fast dynamic response and easy implementation. This paper proposes a model predictive current control for a single-phase cascaded H-bridge converter topology in two modes: symmetrical and asymmetrical in the grid-connection state. The performance principle of an H-bridge converter and its cascaded connection are analyzed. Then, the mathematical model and predictive current control are explained in a grid-connected condition. The performance of the CHB topologies with the proposed predictive current control technique is evaluated by the simulation results in different conditions.
