Abstract
Circuit de commande par augmentation de coefficient d'utilisation de signal du type à proportionnalité temporelle. Le circuit comprend un circuit de sortie d'un signal de sortie représentant une condition d'établissement ou de coupure, une source d'impulsions de fréquence relativement élevée, un ensemble de comptage principal pour compter les impulsions de la source pendant les périodes d'établissement et de coupure d'un signal d'entrée de coefficient d'utilisation variable, le circuit de sortie modifiant le signal de sortie entre des conditions d'établissement et de coupure quand le compte de l'ensemble de comptage principal atteint une première et une seconde valeur prédéterminée de manière que le signal de sortie ait un coefficient d'utilisation correspondant à celui du signal d'entrée et une fréquence bien inférieure à celle du signal d'entrée. Application aux équipements de chauffage et de refroidissement.
