Control of Grid Connected Modular Multilevel Converter
Elektronika ir Elektrotechnika, 2015 This paper describes the control of multilevel voltage source active rectifier connected directly to ac grid. The proposed topology of multilevel converter is composed of three cascaded H-bridge converters (CHB), thus in this case seven level converter. Designed control algorithm provides direct current control in each phase even under unbalanced load.
