Synchronous Control of Modular Multilevel Converters
Proceedings of the IEEE International Symposium on Industrial Electronics ISIE-02, 2002A novel method of direct synchronous pulsewidth modulation (PWM) is applied for control of modular multilevel converters consisting from three standard triphase inverter modules along with an 0.33 p.u. output transformer. The proposed method provides synchronisation of the voltage waveforms for each module and the composed voltage at the output of the ...

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.

Improved Model of Modular Multilevel Converter
2018Voltage sourced converter (VSC) exhibits a brilliant open door in different fields of the power system. Newly introduced modular multilevel converters (MMCs) are expected to replace two- and three-level VSC-based configurations for high-voltage direct current (HVDC) transmission systems due to their advantages in terms of performance, scalability, and ...
