A multilevel converter particularly including one capacitor (C1, C2, ..., Cn) per cell as well as control means including means (VMO1, VMO2, ..., VMOn) for evaluating the average voltage across the terminals of each of the capacitors (C1, C2, ..., Cn), means (VE1, VE2, ..., VEn) for determining any deviation between the evaluated average charging voltage and the rated average charging voltage for each of the capacitors (C1, C2, ..., Cn), as well as complementary control means (MCC1, MCC2, ..., MCCn) for altering the converter control signals in such a way as to reduce said deviation.
Convertisseur multiniveaux comprenant notamment un con- densateur (C1, C2..., Cn), pour chacune de ses cellules ainsi que des moyens de commande comprenant des moyens d'évaluation (VMO1, VMO2..., VMon) de la tension moyenne aux bornes de chacun des condensateurs (C1, C2..., Cn). des moyens (VE1, VE2..., VEn) pour constater, pour chacun desdits condensa- teurs (C1, C2..., Cn), un écart éventuel entre la tension de charge moyenne évaluée et la tension de charge moyenne nom- inale de ce condensateur, ainsi que des moyens de commande complémentaires (MCC1, MCC2..., MCCn) modifiant des signaux de commande du convertisseur dans un sens tel que ledit écart con- staté soit réduit.
