Abstract

SE PRESENTA UN CIRCUITO DE ALIMENTACION ELECTRICA ESTABILIZADO PARA SER UTILIZADO EN UN RECEPTOR DE TELEVISION. POR LO MENOS HAY CONECTADOS DOS RSCS (107, 111) CONECTADOS EN SERIE Y EN SENTIDO DIRECTO ENTRE UN CIRCUITO GENERADOR DE TENSION CONTINUA NO ESTABILIZADO (105) Y UN CIRCUITO DE SALIDA HORIZONTAL (101) QUE SIRVE COMO CARGA. EL TIEMPO DE DESCANSO DE LOS RSCS ES CONTROLADO EN RESPUESTA A LOS IMPULSOS COLECTORES HORIZONTALES GENERADOS DESDE EL CIRCUITO DE SALIDA HORIZONTAL. SI SE AUMENTA EL NUMERO DE LOS RSCS CONECTADOS EN SERIE CON UN AUMENTO DEL NIVEL DE LA TENSION CONTINUA NO ESTABILIZADA SE SUPRIME UN AUMENTO EN VALORES MAXIMOS DE LA CORRIENTE QUE PASA A TRAVES DE LOS RSCS. DE ESTE MODO, LOS RSCS SE APAGAN EN POCO TIEMPO, EVITANDO ASI QUE SE PRODUZCAN OPERACIONES ERRONEAS CAUSADAS POR UN RETARDO DEL TIEMPO DE DESCANSO.
