Abstract

GENERADOR DE IMPULSOS PARA UN SISTEMA DE DEFLEXION HORIZONTAL. CONSTA DE UN CONDENSADOR (220) QUE SE CARGA INICIALMENTE A UN NIVEL DE TENSION DE REFERENCIA DESDE UNA FUENTE DE CORRIENTE (204), EN UNA DURACION DE TIEMPO CONOCIDA, A UN PRIMER REGIMEN; AL FINAL DEL INTERVALO DE CARGA, EL CONDENSADOR HA ACUMULADO UN INCREMENTO CONOCIDO DE CARGA, ESTABLECIENDOSE UN NUEVO NIVEL DE TENSION, CON LO QUE EL GENERADOR ESTA PREPARADO PARA PRODUCIR UN IMPULSO DE SALIDA; DURANTE EL INTERVALO DE TIEMPO EN QUE UNA SEGUNDA FUENTE DE CORRIENTE (210) ESTA CARGANDO EL CONDENSADOR, EL GENERADOR PRODUCE UN IMPULSO DE SALIDA; CUANDO UN CIRCUITO SENSOR (222) DETECTA QUE EL CONDENSADOR SE HA DESCARGADO A NIVEL DE TENSION DE REFERENCIA INICIAL, DESCONECTA LA FUENTE DE CORRIENTE (210) DE DESCARGA DEL CONDENSADOR, TERMINANDO DE ESTE MODO EL IMPULSO DE SALIDA. DE APLICACION EN RECEPTORES DE TELEVISION. T
