Abstract

UNA TENSION BASE DE UN TRANSISTOR REGULADOR (Q2) SE DESARROLLA DURANTE EL FUNCIONAMIENTO NORMAL EN UN CONDENSADOR DE FILTRO (C2) ACOPLADO A UN TRANSFORMADOR DE RETORNO (24) DE UN CIRCUITO DE DEFLECCION HORIZONTAL (Q5, LY, C SUB S). DESPUES DE UNA TRANSICION A UN MODO DE OPERACION DE ESPERA, EL CIRCUITO DE DEFLECCION ESTA DESACTIVADO Y EL CONDENSADOR EMPIEZA A DESCARGARSE. EL EMISOR DEL TRANSISTOR ESTA ACOPLADO A UN CIRCUITO DE CARGA (L3). UNA TENSION DE SUMINISTRO (+V SUB 1) SE ACOPLA AL COLECTOR DEL TRANSISTOR DURANTE LOS MODOS DE ESPERA Y NORMALES. PARA REDUCIR LA CARGA DE UN SUMINISTRO DE ENERGIA DE ESPERA QUE GENERA LA TENSION DEL COLECTOR CUANDO EL CONDENSADOR NO ESTA DESCARGADO DEL TODO, SE PREVEE UNA PARADA ACTIVA (Q3) DEL TRANSISTOR DE REGULACION INMEDIATAMENTE DESPUES DE QUE EL RECEPTOR ENTRA EN EL MODO DE ESPERA PARA ASI PARAR DE FORMA ACTIVA LA CORRIENTE DIRIGIDA POR EL TRANSISTOR.
