Internal Faults in Modular Multilevel Converter
2018 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2018The Modular Multilevel Converter (MMC) has modular and redundant structure, which makes it more reliable during certain fault conditions. Hence MMC technology has received considerable attention among various topologies for interconnecting High Voltage Direct Current (HVDC) grid.

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 ...

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.
