  • Modular multilevel current source and voltage source converters to increase number of output current levels and output voltage levels
    Patent number: 9806633
    Abstract: Embodiments herein provide a modular multilevel converter configured to increase one of number of an output voltage level and an output current level. The modular multilevel converter includes a plurality of legs where each leg includes a plurality of arms. Each arm of the modular multilevel voltage source converter includes a main wave shaping (WS) circuit, an auxiliary WS circuit and an arm inductor. The main WS circuit includes one or more half bridge sub-module(s) that includes a capacitor. The auxiliary WS circuit includes one or more full bridge sub-module(s) that includes a capacitor. Each arm of the modular multilevel current source converter comprises a plurality of half-bridge modules connected in parallel, and a plurality of arm capacitor connected across the plurality of half-bridge modules and one or more auxiliary full bridge module(s).
