Abstract
EN FUENTES DE ALIMENTACION DE CONEXION ES CONOCIDO, EN SITUACIONES DE CONMUTACION CON POTENCIA TRANSMITIDA PEQUEÑA EN CONDICIONES DE SERVICIO CONOCIDAS DE STANDBY, CONTROLAR EL TRANSISTOR DE CONEXION SOLAMENTE CON PAQUETES DE IMPULSOS DIRIGIDOS, ENTRE LOS QUE SE ENCUENTRAN PAUSAS LARGAS. EL OBJETIVO ES CONSEGUIR UNA FUENTE DE ALIMENTACION DE CONEXION PARA UN CONTROL DE PAQUETE DE ESTE TIPO, QUE TRABAJA CON REGULACION PRIMARIA PURA, NO NECESITANDO NINGUN IC ESPECIAL, CONMUTADO AUTOMATICAMENTE ENTRE SERVICIO NORMAL CON PWM Y SERVICIO DE PAQUETE Y DISPONIENDO DE UN ALTO RENDIMIENTO. LA SALIDA DE UN RECTIFICADOR (4) DE ELEMENTO DE MEDIDA EFECTUA UNA DIVISION DE LA TENSION (US) DE DESCONEXION PARA EL TRANSISTOR (T4) DE DESCONEXION A TRAVES DE UN PRIMER CIRCUITO (Z1, T2, T3) CON UN PRIMER UMBRAL DE INDICACION Y A TRAVES DE UN SEGUNDO CIRCUITO (Z1, T5 CONDENSADOR (T4) DE ACOPLAMIENTO EN LA CONDUCCION BASE DE TRANSISTOR (T1) DE CONEXION. ES ADECUADO ESPECIALMENTE PARA FUENTES DE ALIMENTACION SIN ICEN RECEPTORES DE TELEVISION DE POTENCIA PEQUEÑA.
