A Flying-capacitor Modular Multilevel Converter
2018 IEEE 7th International Conference on Power and Energy (PECon), 2018With the increase of HVDC transmission, HVDC grids are the inevitable trend of the future. HVDC DC-DC converters act as the indispensable components to transmit energy and connect HVDC grids with different voltage levels. This paper proposes a flying-capacitor modular multilevel DC-DC converter for HVDC grid connection and offshore wind farm collection

Compact mixed cell modular multilevel converter
2018 IEEE International Conference on Industrial Technology (ICIT), 2018This paper proposes a new hybrid converter as an alternative to alternate arm converter (AAC) and conventional mixed cell modular multilevel converter (MC-MMC). Although the proposed converter evolves from AAC, it resembles a version of the MC-MMC, where the entire low-voltage rated half-bridge (HB) cells in each arm are replaced by one high-voltage HB

A Novel Modular Expandable Multilevel Converter
International Journal of Circuit Theory and ApplicationsABSTRACTMultilevel converters are widely used because of low harmonic content, low switching loss, and low electromagnetic interference. However, when the output voltage level of the traditional multilevel converter is high, it needs many power semiconductors and the control is complicated.
