Abstract

L'INVENTION A POUR OBJET UN CIRCUIT ELECTRONIQUE EN CASCADE COMPRENANT UN CIRCUIT AYANT DES CARACTERISTIQUES COURANT-TENSION INTERELECTRODES CONTROLABLES, ET UN CIRCUIT A DEUX POLES. UN CIRCUIT ELECTRONIQUE COMPREND, EN CASCADE, UN CIRCUIT A DEUX POLES 32 AYANT UNE BORNE D'ENTREE ET UNE BORNE DE SORTIE, ET UN CIRCUIT A CARACTERISTIQUES COURANT-TENSION INTERELECTRODES CONTROLABLES COMPRENANT UNE BORNE D'ENTREE, UNE BORNE DE SORTIE, ET UNE BORNE DE COMMANDE EXTERIEURE, PREVOYANT UN MOYEN DE COMMUTATION AYANT UN CONTACT PRINCIPAL 33 ET DEUX CONTACTS DE COMMUTATION 34-35. LE CONTACT PRINCIPAL 33 EST RELIE A LA BORNE DE COMMANDE 31, LE PREMIER CONTACT DE COMMUTATION 34 A LA BORNE DE SORTIE 37 DU CIRCUIT A DEUX POLES 32 ET LE SECOND CONTACT 35 DE COMMUTATION A LA BORNE D'ENTREE 36 DU CIRCUIT A DEUX POLES 32, ET UNE CONNEXION DIRECTE EST PREVUE ENTRE LA BORNE DE SORTIE 37 DU CIRCUIT A DEUX POLES ET LA BORNE D'ENTREE DU CIRCUIT 30 A CARACTERISTIQUES COURANT-TENSION INTERELECTRODES CONTROLABLES.
