Abstract

L'invention porte sur un système de commande de charges électriques, plus particulièrement d'unités d'éclairage. Ce système comprend au moins un élément transformateur ayant une multitude de prises disposées de manière à fournir des rapports de tension supérieurs, égaux ou inférieurs à la tension d'alimentation nominale qui est acheminée avec la charge. Ce système comporte également un organe de commutation sélective des prises à l'aide d'éléments de commutation permettant de combiner une multitude de niveaux de tension de sortie dans un certain nombre d'étapes bien supérieur au nombre de prises et au nombre d'éléments de commutation qui sont commandés par un microprocesseur doté d'un programme et d'une horloge en temps réel. Cet agencement permet de faire varier la tension acheminée vers les lampes ou d'autres charges et de la commander selon différents créneaux temporels dans une journée pendant que le système fonctionne.
