Abstract

CE CIRCUIT QUI EST DESTINE A REPARTIR LE COURANT DE CHARGE ENTRE LES TRANSISTORS 10, 11, COMPREND UNE RESISTANCE DE MESURE DE COURANT 14 POUR CHAQUE TRANSISTOR ET DES CIRCUITS DE PROTECTION INDEPENDANTS COMMANDES PAR LA CHUTE DE TENSION AUX BORNES DE LA RESISTANCE DE MESURE 14 ASSOCIEE, AFIN DE LIMITER LE COURANT DANS CHAQUE TRANSISTOR DE PUISSANCE A UNE VALEUR DE SECURITE. CHAQUE CIRCUIT DE PROTECTION COMPREND DES DIODES ZENER 26, 27, 30, 31 ET DES RESISTANCES 24, 25, 28, 29 QUI ASSURENT LA LIMITATION DU COURANT EN FONCTION DE LA TENSION AUX BORNES DES TRANSISTORS DE PUISSANCE.
