Abstract

L'invention entre dans le domaine de la régulation des moteurs. Dispositif de commande d'un moteur asynchrone alimenté à fréquence variable par un réseau électrique triphasé par l'intermédiaire d'un pont redresseur à thyristors, d'une cellule de filtrage du courant redressé comprenant une inductance en série et un condensateur en parallèle, et d'un pont onduleur à thyristors, à commutation forcée, les thyristors du pont onduleur étant commandés par des impulsions élaborees par un circuit de commande recevant en entrée un signal proportionnel à la tension d'alimentation du pont onduleur, les thyristors du pont redresseur étant commandés par des signaux élaborés par un circuit de commande de portes recevant à son entrée une tension de commande élaborée par un régulateur recevant une tension de consigne et une valeur mesurée proportionnelle à la tension aux bornes du moteur, caractérise en ce que la sortie du régulateur comprend un moyen pour que la tension de commande reste inférieure à une valeur telle que le rapport de la tension d'alimentation du moteur à sa fréquence ne dépasse pas une valeur maximale donnée.
