Abstract

CIRCUITO DE DEFLEXION CON CORRECCION DE LINEALIDAD PARA APARATOS DE TELEVISION. ESTA FORMADO POR UN GENERADOR (50) DE ONDA RECTANGULAR QUE PRODUCE UNA TENSION (22) DE EXCITACION, LA CUAL SE APLICA AL PRIMARIO (3A) DE UN TRANFORMADOR DE POTENCIA (23B, C, D, E) DE LOS QUE UNO (23B) CONSTITUYE UNA FUENTE DE ALIMENTACION (52) PARA UN GENERADOR DE DEFLEXION HORIZONTAL (30). ESTE GENERADOR SE COMPONE DE UN OSCILADOR Y EXCITADOR HORIZONTAL (31), UN TRANSISTOR DE SALIDA (3) QUE ACTUA COMO CONMUTADOR, UN DIODO AMORTIGUADOR (34) Y DOS CONDENSADORES CONECTADOS EN SERIE (35, 36).
