Abstract

EL PRESENTE INVENTO SE REFIERE A UN CIRCUITO DE CONTROL QUE CONSTA DE: UN CONMUTADOR DE POTENCIA BIPOLAR (4) EN SERIE CON LA PRIMARIA DE UNA BOBINA DE ENCENDIDO (2) Y UNA RESISTENCIA DE DETECCION (R1) ASOCIADA A UN DIVISOR DE TENSION (R2,R3) QUE SUMINISTRA UNA TENSION VD; UN AMPLIFICADOR-COMPARADOR CONTROLADO (9) CUYA PRIMERA ENTRADA RECIBE LA TENSION DETECTADA Y LA SEGUNDA RECIBE UNA TENSION DE REFERENCIA (8), ESTANDO LA SALIDA ENLAZADA A LA BASE DEL CONMUTADOR (4). EL AMPLIFICADOR-COMPARADOR ACTUA LIMITANDO LA CORRIENTE BASE CUANDO LA TENSION DETECTADA SE APROXIMA A LA TENSION DE REFERENCIA; UNA RESISTENCIA EN SERIE (R10) ENTRE LA SALIDA DEL AMPLIFICADOR-COMPARADOR (9) Y LA BASE DEL CONMUTADOR (4); UN AMPLIFICADOR DIFERENCIAL (11) CUYAS ENTRADAS ESTAN CONECTADAS A LOS BORNES DE LA RESISTENCIA EN SERIE Y CUYA SALIDA ESTA ENLAZADA A LA PRIMERA ENTRADA DEL AMPLIFICADOR-COMPARADOR.
