Hybrid modular multilevel converter (MMC) applications under over-modulation [PDF]
, 2021 The Modular Multilevel Converter (MMC) has become a prominent converter topology due to its several advantages: high modularity, high scalability, low harmonic distortion, and high efficiency. In particular, due to its modular structure, it is possible to increase its voltage rating by stacking extra cells. The MMC has been successfully applied to high

Mechanism and suppression of breaking overvoltage of DC circuit breakers
High Voltage, Volume 10, Issue 1, Page 32-46, February 2025.Abstract The occurrence of breaking overvoltage in a DC circuit breaker (DCCB) poses a potential threat to the safe operation of a DC grid. Based on the structure of the ±10 kV three‐terminal DC distribution network, this paper sets up the medium‐voltage DCCB and formulates a fault protection strategy.

Modulation, control, and performance analysis of asymmetric modular multilevel converter (A‐MMC)
IET Power Electronics, 2018 Modular multilevel converters (MMC) have proven to be a viable candidate for high‐voltage direct current transmission systems. Here, asymmetric modular multilevel converters (A‐MMC) are introduced wherein each series connected module has two half‐bridge (HB) submodules, with asymmetric voltage rating.
