Abstract

L'invention porte sur un appareil de commande à adaptation de courant pour l'adaptation d'une pluralité de sources de courant et d'une pluralité de dispositifs d'écoulement de courant, la pluralité de dispositifs d'écoulement de courant ayant une valeur de courant d’attaque commandée par un processeur de commande en fonction d'un courant de commande de référence, et chaque sortie de la pluralité de dispositifs d'écoulement de courant étant connectée à un nœud de sortie commun; un circuit de rétroaction comportant une entrée connectée au nœud de sortie commun et une sortie connectée au processeur de commande, le circuit de rétroaction étant configuré de façon à faire correspondre une tension au niveau du nœud de sortie commun à une tension de référence par communication d'un signal au processeur de commande afin d'ajuster le courant d’attaque de référence.
