Abstract

FUENTE DE ALIMENTACION BIFURCADA, REGULADA. LA FUENTE DE ALIMENTACION REGULADA EMPLEA DOS FUENTES DE ALIMENTACION SEPARADAS (28, 30) QUE ESTAN CONECTADAS EN SERIE, MEDIANTE UN ELEMENTO DE IMPEDANCIA VARIABLE, COMO UN TRANSISTOR (32), CONECTADO ENTRE LAS DOS FUENTES DE ALIMENTACION. LA TENSION DE SALIDA DE LA FUENTE DE ALIMENTACION ES IGUAL A LA SUMA DE LAS TENSIONES DE LAS FUENTES DE ALIMENTACION INDIVIDUALES MENOS UNA CAIDA DE TENSION A TRAVES DEL ELEMENTO DE IMPEDANCIA VARIABLE. UN CIRCUITO SENSOR (38) QUE EMPLEA BIFURCACIONES DE MODO DE RESERVA Y ACTIVO (40, 42) SE ACOPLA ENTRE LOS TERMINALES DE SALIDA DE LA FUENTE DE ALIMENTACION PARA EL CONTROL DEL ELEMENTO DE IMPEDANCIA VARIABLE. LA BIFURCACION ACTIVA DEL SENSOR SE CONECTA CONMUTABLEMENTE A UN TERMINAL DE ALIMENTACION DE SALIDA (22) DE LA FUENTE PARA QUE ESTE EN FUNCIONAMIENTO SOLO DURANTE EL MODO ACTIVO. LA BIFURCACION DE RESERVA COMPRENDE UNA RED RESISTIVA (52) ACOPLADA A UN DIODO DE REFERENCIA (44) MIENTRAS QUE LA BIFURCACION ACTIVA COMPRENDE UN AMPLIFICADOR DE RETROALIMENTACION (58) ACOPLADO A UN DIODO DE REFERENCIA
