Abstract
DISPOSITIVO DE CONEXION REGULADORA PARA GENERAR UNA TENSION DE SALIDA CONSTANTE A PARTIR DE TENSIONES DE ENTRADA VARIABLES. DEBIDO A LA TENSION DE REFERENCIA (UB) QUE YACE EN EL DIODO ZENER (Z), ES MENOR QUE LA TENSION (U1) DE ENTRADA, SE CONTROLA EL TRANSISTOR (T1) Y EL TRANSISTOR (T3). POR SU PARTE EL TRANSISTOR (T3) CONTROLA AL TRANSISTOR (T2), CON LO QUE EL CONDENSADOR (C) SE CARGA HASTA LA TENSION DE SALIDA (42) EN EL MOMENTO QUE TENGA EL MISMO VALOR QUE LA TENSION DE ENTRADA (U1), REDUCIENDO EN LA MAGNITUD CORRESPONDIENTE A LA TENSION DE TRANSISTOR (T2). AL SER LA TENSION (U1) INFERIOR A LA TENSION (UB) SE BLOQUEAN LOS TRANSISTORES (T1) Y (T3), CON LO CUAL SE BLOQUEA EL TRANSISTOR (T2) E IMPIDE LA DESCARGA DEL CONDENSADOR (C).
