Abstract

RECEPTOR DE TELEVISION CON UNA FUENTE DE ALIMENTACION CONMUTADA PARA REGULAR UNA TENSION DE SALIDA, QUE INCLUYE UN TRANSFORMADOR DE POTENCIA (LP36) CON UN PRIMARIO (W1) ACOPLADO A UNA TENSION NO REGULADA (VIN) MEDIANTE UN TRANSISTOR DE POTENCIA. EL TRANSISTOR DE POTENCIA SE CONTROLA MEDIANTE PULSOS (VCON) DE LA SALIDA DE UN CONTROLADOR (20). PARA BARRER LA CARGA BASE-EMISOR DEL TRANSISTOR DE POTENCIA PARA DAR FIN A LA CONDUCCION COLECTOR-EMISOR, LA BASE DEL TRANSISTOR DE POTENCIA SE ACOPLA A LA SALIDA DEL CONTROLADOR GENERADOR DE PULSOS POR MEDIO DE UN CONDENSADOR (CP24) EN PARALELO CON AL MENOS UN DIODO (DP24, 26, 27). DURANTE UN PULSO DEL CONTROLADOR, EL CONDENSADOR SE CARGA A UNA TENSION IGUAL A LA CAIDA DESVIADA HACIA ADELANTE EN EL/LOS DIODO/S. AL FINAL DE UN PULSO A LA SALIDA DEL CONTROLADOR, LA TENSION EN EL CONDENSADOR PROPORCIONA UNA TENSION NEGATIVA EN LA BASE DEL TRANSISTOR, ELIMINANDO ASI LA CARGA BASE-EMISOR Y DESCONECTANDDO EL TRANSISTOR BRUSCAMENTE. PARA ASEGURAR ESTA FUNCIONDEL CONDENSADOR INCLUSO EN EL ENCENDIDO POR ENCHUFADO, SE PRECARGA EL CONDENSADOR POR MEDIO DE UN RESISTOR (RP324) ACOPLADO ENTRE LA SALIDA DEL CONTROLADOR (PATA 14) Y LA ENTRADA DE TENSION NO REGULADA (VIN).
