Abstract

a. Circuit de détection d'une tension continue déséquilibrée. b. Détecteur caractérisé par un circuit de décalage de niveau continu, un moyen pour relier le second transistor de commutation au filtre passe-bas par le circuit de décalage de niveau continu et un moyen de détection relié au premier et au second transistors de commutation pour créer un signal de commande lorsque la tension continue, déséquilibrée, dépasse une valeur prédéterminée.
