Abstract

L'invention concerne un circuit électrique destiné à délivrer de l'énergie électrique avec des fonctions de commande et de protection pour l'attaque d'une charge telle qu'un réseau de diodes électroluminescentes ou similaire. Le circuit électrique comprend un convertisseur, un module de retour d'informations de tension, un module de retour d'informations de courant et un dispositif de commande. Le convertisseur est configuré pour recevoir de l'énergie électrique d'une source d'énergie et pour délivrer l'énergie électrique attaquant la charge. Le module de retour d'informations de tension est configuré pour générer un premier signal de retour d'informations basé sur la tension de l'énergie électrique délivrée. Le module de retour d'informations de courant est configuré pour générer un second signal de retour d'informations basé sur l'intensité de l'énergie électrique délivrée. Le dispositif de commande est configuré pour recevoir le premier signal de retour d'informations et le second signal de retour d'informations et pour commander le convertisseur afin que celui-ci reçoive et délivre l'énergie électrique sur la base du premier signal de retour d'informations et du second signal de retour d'informations.
