Modeling, control, and reduced-order representation of modular multilevel converters
(Elsevier Science Sa, 2018-10)
This paper presents a reduced-order model of the modular multilevel converter (MMC) for electromechanical transient simulations and small-signal analysis. The MMC model is firstly developed in detail; then, simplifications ...
Experimental validation of a nested control system to balance the cell capacitor voltages in hybrid MMCs
(IEEE, 2021)
In a hybrid modular multilevel converter (MMC), capacitor voltage balance between the Full-Bridge Sub-Modules (FBSMs) and Half-Bridge Sub-Modules (HBSMs) is only possible when the arm currents are bipolar. For a grid-connected ...

Sliding Mode Control Of The Modular Multilevel Converter
(2019)
The modular multilevel converter (MMC) has become the most promising converter topology for medium- and high-power applications. In this paper, a sliding mode control (SMC) based method is proposed for the MMC. Based on ...
The Application of the Modular Multilevel Matrix Converter in HighPower Wind Turbines
(2016)
The trend in wind turbines has shown an ongoing power rating growth, reaching sizes up to 10 MW.
Multilevel converters have therefore become a favourable solution for Multi-MW Wind Energy
Conversion Systems (WECSs), due ...
Decoupled Current Model and Control of Modular Multilevel Converters
(2015)
Modular multilevel converters offer several benefits, such as high scalability and power quality, which are particularly advantageous for high-voltage dc transmission systems. However, the control of such converters is ...

A Switched-Diode Topology for Cascaded Multilevel Converters with Reduced Number of Switches
(Institute of Electrical and Electronics Engineers Inc., 2022)
In medium-voltage applications, the main issue with multilevel converters is that they require a large number of semiconductor switches when higher voltage levels are required. The main objective of this paper is to propose ...
