Abstract

Procédé et dispositif de protection contre les surcharges et les courts-circuits d'éléments de pilotage de sortie, utilisant un circuit qui fonctionne à plusieurs niveaux de tension de commande et dans lequel au moins un élément de pilotage de sortie (Q31, Q41) est commandé dans une situation normale par une valeur de référence (+Vd) établie indépendamment de la commande extérieure (I1-I7), tandis que dans une situation de court-circuit ou de surcharge l'élément de pilotage reçoit une tension de commande pendant de courts instants seulement, et dans lequel la valeur de référence commence à chuter rapidement lorsque le courant de charge de l'élément de pilotage de sortie dépasse une limite fixée.
