Abstract

CUANDO UN CIRCUITO DE DEFLECCION VERTICAL CON UN IC DEL TIPO TDA 8178FS O TDA 8179FS DEBE SER OPERADO A UNA FRECUENCIA DE DEFLECCION INCREMENTADA DE 100 HZ Y EN TIEMPO DE RETORNO REDUCIDO, DEBE SER INCREMENTADA LA TENSION DE OPERACION, ALCANZANDO DE ESTA FORMA LA DISIPACION DE POTENCIA. EL OBJETIVO ES PERMITIR LA OPERACION DE ESTE CIRCUITO A 100 HZ CON RETORNO RAPIDO SIN INCREMENTAR LA DISIPACION DE POTENCIA. LA CLAVIJA (2) DEL IC SE CONECTA DURANTE EL RETORNO MEDIANTE UN INTERRUPTOR (3) A LA SEGUNDA TENSION (US2) DE OPERACION QUE ES MAYOR QUE LA PRIMERA (US1). ADECUADO ESPECIALMENTE PARA RECEPTORES DE TELEVISION CON 16:9 CRT Y UNA FRECUENCIA VERTICAL DE 100 HZ.
