Modelling and Control of the Modular Multilevel Converter (MMC)
Energy Procedia, 2012 AbstractThe Modular Multilevel Converter (MMC) represents an emerging topology with a scalable technology making high voltage and power capability possible. The MMC is built up by identical, but individually controllable submodules. Therefore the converter can act as a controllable voltage source, with a large number of available discrete voltage steps.

Modular Multilevel Converter (MMC) Modeling Considering Submodule Voltage Sensor Noise
IEEE Transactions on Power Electronics, 2021 The modular multilevel converter (MMC) is a popular topology in medium- and high-voltage applications, and many efforts have been spent on MMC modeling. However, the impact of submodule voltage sensor noise (SVSN), which becomes more severe due to increasing switching speed of power semiconductors and compact submodule design, has not been considered ...

Differential Flatness-Based, Full-Order Nonlinear Control of a Modular Multilevel Converter (MMC)
IEEE Transactions on Control Systems Technology, 2022 Modular multilevel converter (MMC) is an attractive topology in industrial applications such as high-voltage direct current (HVdc) transmission system where fast power control is required. The most conventional control method for MMC uses cascaded structures, where the power transmission and internal energy dynamic (outer loops) is limited by the ...
