Modular Analytical Modeling of the Modular Multilevel Converter (MMC)
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 ...
