Abstract

CE CIRCUIT ELECTRIQUE COMPORTE UN TRANSISTOR PILOTE 12, A L'EMETTEUR DUQUEL EST RELIEE LA CHARGE 11 DE FACON QU'IL FONCTIONNE EN EMETTEUR FOLLOWER. UNE RESISTANCE 14 EST MONTEE ENTRE LA BASE ET L'EMETTEUR DU TRANSISTOR PILOTE ET UN CIRCUIT DE COMMANDE 16 EST PREVU POUR LA TENSION APPLIQUEE A LA BASE DE CE TRANSISTOR. POUR VERIFIER LA CONTINUITE DE LA CHARGE, UN TRANSISTOR DE DETECTION 17 A SON CIRCUIT BASE-EMETTEUR MONTE ENTRE LES BORNES DE LA RESISTANCE 14. LORSQUE LE COURANT TRAVERSE LA CHARGE, LE TRANSISTOR DETECTEUR PEUT DEVENIR PASSANT, MAIS IL SE BLOQUE LORSQUE LE CIRCUIT EST OUVERT DANS LA CHARGE.
