Abstract

L'INVENTION CONCERNE LES MESURES SUR LES THYRISTORS. UNE FIBRE OPTIQUE 6 EST PLACEE EN CONTACT OPTIQUE AVEC UN THYRISTOR 13 DANS LE BUT DE TRANSMETTRE UN SIGNAL LUMINEUX EMIS PAR LE THYRISTOR ETOU EMIS VERS LE THYRISTOR ET TRAVERSANT CE DERNIER, CE QUI PERMET D'OBTENIR DES SIGNAUX QUI DEPENDENT DU COURANT, DE LA TEMPERATURE ETOU DE LA TENSION DANS LE THYRISTOR, A CAUSE DES RECOMBINAISONS ELECTRONS-TROUS DANS CELUI-CI. APPLICATION A LA PROTECTION DES THYRISTORS DE PUISSANCE.
