Abstract

L'INVENTION CONCERNE UN CIRCUIT TRANSISTORISE FLOTTANT DE COMMUTATION. ELLE SE RAPPORTE A UN CIRCUIT QUI COMPREND UN COUPLEUR OPTIQUE QUI ISOLE UNE SOURCE DE SIGNAUX DE COMMANDE PAR RAPPORT AU CIRCUIT DE COMMUTATION. UNE ALIMENTATION CONTINUE FLOTTANTE TRANSMET DES TENSIONS DE FONCTIONNEMENT DE NIVEAU LOGIQUE REFERENCEES PAR RAPPORT A LA TENSION DE LA BORNE DE SORTIE DU CIRCUIT. UN ETAGE DE SORTIE EST MIS A L'ETAT CONDUCTEUR OU NON CONDUCTEUR PAR UN CIRCUIT LOGIQUE RECEVANT LE SIGNAL DE SORTIE DU COUPLEUR OPTIQUE. APPLICATION AUX CONVERTISSEURS DE COURANT.
