Abstract

CIRCUITO DE CONMUTACION CON TRANSISTORES. A UNA SEÑAL DE ENTRADA (E), UN TRANSISTOR (T1) ENTRA EN CONDUCCION PROVOCANDO LA SATURACION DE UN TRANSITOR PRINCIPAL (T5) QUE DA CORRIENTE A UNA CARGA (RC). LA CORRIENTE, EN BASE DEL TRASITOR PRINCIPAL (T5), ES ESTABILIZADA POR EL EFECTO DE UN TRANSISTOR (T4), UNA RESISTENCIA (R8), UN DIODO ZENER (Z1) Y UN CONDENSADOR (C1) QUE FIJAN LA TENSION DE ALIMENTACION (V5). LA CARGA (RC) DEJA DE RECIBIR CORRIENTE CUANDO DESAPARECE LA SEÑAL DE ENTRADA (E). EN CASO DE CORTOCIRCUITO EXTERNO, LA ENTRADA, EN CONDUCCION DE UN TRANSISTOR (T.3A), PROVOCA EL CORTE DEL TRANSISTOR PRINCIPAL (R5) ANTES DE SU DESTRUCCION. DE APLICACION DE DETECTORES DE PROXIMIDAD DEL TIPO INDUCTIVO O POR CELULA FOTOELECTRICA.
