Full-bridge modular multilevel converter (FB-MMC) with extended control range [PDF]
AFRICON 2015, 2015 This paper presents an attractive control scheme that decouples cell capacitor voltage regulation of the FB-MMC from the dc link voltage regulation. This is achieved by manipulating both ac and dc components of modulation functions. The dc component of modulation function is used to regulate the cell capacitor voltages independent of the dc link ...

Modular Analytical Modeling of the Modular Multilevel Converter (MMC)
, 2021 Cet article présente une modélisation du convertisseur modulaire multiniveaux (MMC) qui se veut modulaire à l'image de sa topologie. La modélisation du MMC est composée de deux parties, une partie bas-niveau qui traite de la description des sous-modules (SM) qui composent le MMC et une partie haut-niveau qui représente le comportement du MMC avec ses ...

High Voltage, EarlyView.ABSTRACT Amid the ongoing global energy transition, the short‐circuit ratios of AC power grids are continuously decreasing. Grid‐forming voltage source converter‐based high voltage direct current transmission (GFM VSC‐HVDC) systems have therefore come to the forefront of attention.
