Abstract

LE CONVERTISSEUR COMPREND UN CIRCUIT MAGNETIQUE DE TRANSFERT BRANCHE ENTRE LE POINT MILIEU D'UN PONT DE CONDENSATEURS ET LE POINT MILIEU D'UN MUTATEUR EN PONT CONSTITUE DE DEUX THYRISTORS RELIES PAR DEUX BOBINES D'INDUCTANCES BRANCHEES EN SERIE ET COUPLEES PAR INDUCTION SUR UN MEME CIRCUIT MAGNETIQUE, DE DEUX DIODES MONTEES EN ANTI-PARALLELE SUR LES THYRISTORS ET LE POINT MILIEU DES DEUX BOBINES D'INDUCTANCE, ET DE DEUX CONDENSATEURS EN PARALLELE SUR LESDITES DIODES, LES EXTREMITES DU PONT DE CONDENSATEURS ET DU MUTATEUR ETANT RELIEES PAR DEUX INDUCTANCES; LE CIRCUIT ETANT ALIMENTE PAR LE SECTEUR REDRESSE; UN MOYEN DE PROTECTION ETANT MONTE ENTRE LA SORTIE DU MOYEN REDRESSEUR, ET LEDIT CIRCUIT ONDULEUR, TANDIS QU'UN MULTIPOLE ASSURE LA COMMANDE DES THYRISTORS. L'INVENTION EST NOTAMMENT UTILISEE DANS TOUS LES CAS OU LES VARIATIONS DYNAMIQUES DE CHARGE SONT SUSCEPTIBLES D'ENTRAINER LA DESTRUCTION D'UN TRANSFORMATEUR.
