Abstract

PROCEDIMIENTO PARA LA GENERACION DE UN IMPULSO DE EXCITACION RETARDADO EN UN SISTEMA DE DEFLEXION Y PARA LA GENERACION DE UN IMPULSO DE DESCONEXION RETARDADO EN UNA FUENTE DE ALIMENTACION PARA RECEPTORES DE TELEVISION. UNA ENTRADA ACOPLADA A UN GENERADOR DE ONDAS DE DIENTES DE SIERRA (92) RECIBE IMPULSOS QUE SE MANTIENEN EN SINCRONISMO DE FASE Y FRECUENCIA CON LOS IMPULSOS DE SINCRONIZACION DE LA SEÑAL DE VIDEO (12); LA ONDA DE DIENTE DE SIERRA SE ALIMENTA A UN COMPARADOR (70) EN EL CIRCUITO DE DEFLEXION HORIZONTAL (110), DONDE SE COMPARA CON LA TENSION CONTINUA, RESULTANTE DE LA COMPARACION DE FASE DE LOS IMPULSOS DE SINCRONIZACION Y RETROCESO, PARA DETERMINAR EL TIEMPO DE GENERACION RETARDADA DE LA SEÑAL DE DEFLEXION HORIZONTAL SUCESIVA. LA ONDA DE DIENTE DE SIERRA SE ALIMENTA TAMBIEN A UN SEGUNDO COMPARADOR (80) EN LA FUENTE DE ALIMENTACION PARA DETERMINAR EL TIEMPO DE GENERACION RETARDADA DE LAS SEÑALES DE DESCONEXION SUCESIVAS PARA EL DISPOSITIVO SCR DEL CIRCUITO REGULADOR (100).
