Abstract

EN UN APARATO DE TELEVISION DISPONIENDO DE DIFERENTES MODOS DE OPERACION CON PANTALLA EN EXCESO, LA TENSION DE CONVERGENCIA ES EFECTIVA SOLAMENTE DURANTE PARTE DEL PERIODO DE DEPRESION. LA AMPLITUD MAXIMA Y MEDIA ARITMETICA DE LA TENSION (UF) DE CONVERGENCIA DINAMICA DEBER SER LA MISMA EN TODOS LOS MODOS DE OPERACION, DESDE QUE LA TENSION DE CONVERGENCIA DEL ELECTRODO DE CONVERGENCIA ES SUMINISTRADA MEDIANTE UN ACOPLAMIENTO DE TENSION ALTERNATIVA. EL OBJETIVO ES SUMINISTRAR UN CIRCUITO SIMPLE QUE ASEGURA LA MISMA MEDIA ARITMETICA PARA LA TENSION DE CONVERGENCIA EN TODOS LOS MODOS DE OPERACION. LA TENSION (UF) DE CONVERGENCIA ES CONECTADA MEDIANTE LOS TIEMPOS (0 TAL FORMA QUE LA MEDIA ARITMETICA DE LA TENSION (UF) DE CONVERGENCIA ES LA MISMA PARA TODOS LOS MODOS DE OPERACION. ADECUADO ESPECIALMENTE PARA RECEPTORES DE TELEVISION CON 16:9 CRT O RECEPTORES DE TELEVISION DE PROYECCION.
