Abstract
UN RECEPTOR DE TELEVISION TIENE UNA ALIMENTACION ELECTRICA EN MODO CONMUTADO (TP29, LP36) PARA REGULAR TENSIONES DE SALIDA QUE INCLUYE LA SALIDA B + A UN TRANSFORMADOR DE RETRACCION DEL HAZ (FBT), MEDIANTE GENERACION DE IMPULSOS DE SALIDA A UN TRANSFORMADOR ELECTRICO (LP36). SE ACOPLA UN CONTROLADOR (20) PARA LA ALIMENTACION ELECTRICA EN DOS BUCLES DE RETROALIMENTACION, UNO SENSIBLE A UN MODULADOR DE ANCHO DE IMPULSO (92) ACOPLADO AL TRANSFORMADOR DE RETRACCION DEL HAZ Y EL OTRO QUE COMPARA LA TENSION DE SALIDA CON UNA REFERENCIA INTERNA (EN 34) PARA ACTIVIDAD DE FUNCIONAMIENTO LIBRE. EL PRIMER BUCLE DE RETROALIMENTACION PRECEDE Y ES ACTIVO EN EL MODO DE FUNCIONAMIENTO DEL RECEPTOR DE TELEVISION. EN EL MODO DE ESPERA CUANDO NO HAY IMPULSOS DE RELACION HORIZONTAL, SE HACE CARGO EL SEGUNDO BUCLE DE RETROALIMENTACION. EL SEGUNDO BUCLE DE RETROALIMENTACION TIENE UN NIVEL DE REFERENCIA DISTINTO AL PRIMERO, DE TAL FORMA QUE CUANDO SE CONMUTA DEL MODO DE FUNCIONAMIENTO AL MODO DE ESPERA SE PRODUCEUN INTERVALO DE TRANSICION EN EL QUE EL CONTROLADOR NO ENVIA IMPULSOS, CAUSANDO, DE ESTE MODO, QUE CAIGA LA TENSION B + AL TRANSFORMADOR DE RETRACCION DEL HAZ. DURANTE ESTE INTERVALO DE TRANSICION, CONTINUAN EMITIENDOSE SEÑALES DE EXPLORACION HORIZONTAL EN AMPLITUD DE CAIDA, Y SE ENVIA UNA SEÑAL A LOS EXCITADORES DEL TUBO DE IMAGEN (84), DEBILITANDOSE, DE ESTE MODO, LA IMAGEN Y DISPERSANDO LA TENSION DEL ANODO TERMINAL DEL ANODO DE LA PANTALLA (CSC). SE UTILIZA LA REAPARICION DE LOS IMPULSOS DEL CONTROLADOR, CUANDO HA CAIDO LA TENSION DE SALIDA DEL TRANSFORMADOR DE POTENCIA (LP36) AL NIVEL NUEVO DE REFERENCIA INFERIOR, PARA LA OPERACION, POSITIVAMENTE, DE CONMUTACION DEL RECEPTOR CUANDO CONCLUYE EL INTERVALO DE TRANSICION.
