RADIOLOGICAL GENERATOR INCLUDING AN INVERTER FEEDING ITS HIGH VOLTAGE TRANSFORMER

Abstract

Abstract Translated from French L'INVENTION CONCERNE UN GENERATEUR RADIOLOGIQUE COMPORTANT UN ONDULEUR ALIMENTANT SON TRANSFORMATEUR A HAUTE TENSION. DANS LE DISPOSITIF EST PREVU UN REDRESSEUR RESEAU 1 QUI EST UN REDRESSEUR TRIPHASE RACCORDE AU CIRCUIT SERIE FORME DE DEUX CONDENSATEURS 3, 4 AU POINT DE JONCTION DESQUELS EST RACCORDE LE CONDUCTEUR NEUTRE, TANDIS QU'EN PARALLELE AVEC LE CIRCUIT SERIE DU CONDENSATEUR 3, 4 EST BRANCHE UN CIRCUIT SERIE FORME D'UN TRANSISTOR 6, DE DEUX INDUCTANCES 7, 8 ET D'UN SECOND THYRISTOR 9, DES DIODES 11, 12 ETANT BRANCHEES SUIVANT UN MONTAGE ANTI-PARALLELE AVEC LES THYRISTORS, LES POINTS DE JONCTION DES INDUCTANCES ET DES CONDENSATEURS ETANT RELIES ENTRE EUX PAR UN CONDENSATEUR A LAME VIBRANTE 13 SUR LEQUEL EST PRELEVEE LA TENSION DE SORTIE. APPLICATION NOTAMMENT AUX INSTALLATIONS DE RADIODIAGNOSTIC. THE INVENTION RELATES TO A RADIOLOGICAL GENERATOR INCLUDING AN INVERTER FEEDING ITS HIGH VOLTAGE TRANSFORMER. A NETWORK 1 RECTIFIER IS PROVIDED IN THE DEVICE, WHICH IS A THREE-PHASE RECTIFIER CONNECTED TO THE SERIES CIRCUIT IN THE FORM OF TWO CAPACITORS 3, 4 AT THE JUNCTION POINT TO WHICH THE NEUTRAL CONDUCTOR IS CONNECTED, WHILE IN PARALLEL WITH THE SERIES CIRCENSOR 3, OF THE 4 A SERIAL CIRCUIT SHAPED IN THE FORM OF A TRANSISTOR 6, TWO INDUCTORS 7, 8 AND A SECOND THYRISTOR 9, DIODES 11, 12 BEING CONNECTED FOLLOWING AN ANTI-PARALLEL ASSEMBLY WITH THE THYRISTORS, THE JUNCTION POINTS OF THE INDUCTORS AND OF THE CAPACITORS BEING CONNECTED TO ONE Another BY A VIBRATING BLADE CAPACITOR 13 FROM WHICH THE OUTPUT VOLTAGE IS TAKEN. APPLICATION IN PARTICULAR TO RADIODIAGNOSIS INSTALLATIONS.
