Abstract

UN AMPLIFICADOR DE DESVIACION VERTICAL (20) DE UN APARATO DE VISUALIZACION DE VIDEO INCLUYE: UNA PRIMERA (Q1), Y UNA SEGUNDA (Q2) ETAPAS DE SALIDA DE UN AMPLIFICADOR DE TRANSISTOR CON LA ULTIMA ETAPA DE AMPLIFICACION MONTADAS EN PILAR TOTEMICO, EN CONFIGURACION CONTRAFASICA. UN BOBINADO DE DESVIACION VERTICAL (L SUB V) ESTA ACOPLADA A LAS ETAPAS DE SALIDA EN UNA TERMINAL DE SALIDA DE UN AMPLIFICADOR DE DESVIACION (22). UN CONDENSADOR-S (C1) ESTA ACOPLADO AL BOBINADO DE DESVIACION (L SUB V) EN UNA SEGUNDA TERMINAL (21) LEJOS DE LA TERMINAL DE SALIDA (22). EL ORIGEN (23) DE SEÑALES DE PROPORCION DE LA DESVIACION, SE ACOPLA AL AMPLIFICADOR DE DESVIACION (20) PARA GENERAR UNA CORRIENTE DE DESVIACION (I SUB V) EN EL BOBINADO DE DESVIACION (L SUB V). UN CIRCUITO GENERADOR DE CORRIENTE BASE (40) ESTA ACOPLADO A UNA (Q1) DE LAS ETAPAS DE SALIDA DEL AMPLIFICADOR TRANSISTOR PARA DARLE CORRIENTE BASE (I1). LA TENSION DEL CONDENSADOR-S (V1) SE APLICA AL CIRCUITO GENERADOR DE CORRIENTE BASE (40) PARA PERMITIR LA CONDUCCION DE CORRIENTE BASE (I1) EN LA ETAPA DE SALIDA DE UN UNICO AMPLIFICADOR (Q1). CUANDO SE PONE EN MARCHA POR PRIMERA VEZ EL APARATO DE VISUALIZACION DE VIDEO, EL CONDENSADOR-S DESCARGADO INICIALMENTE (C1) SE VA CARGANDO LENTAMENTE DESDE UN SUMINISTRO DE CORRIENTE DC (+30V), PARA RETRASAR LA PRODUCCION DE DESVIACION VERTICAL HASTA ACABAR LA DESIMANTACION DEL TUBO DE IMAGEN. UN SUMINISTRO DE CORRIENTE DC (16) CONECTADO AL ACCIONAR UN MANDO (15) PRODUCE UN NIVEL DE DC (+DC2) SUFICIENTE PARA ACCIONAR EL AMPLIFICADOR DE DESVIACION ANTES DE QUE TERMINE LA DESIMANTACION.
