Abstract
CIRCUITO DE CORRECCION DE DISTORSION GEOMETRICA NORTE-SUR DEL CAMPO DE CONVERGENCIA DE UN TUBO DE RAYOS CATODICOS. EL CIRCUITO COMPRENDE UN ARROLLAMIENTO DE DEFLEXION DE CAMPO CON SU AMPLIFICADOR CORRESPONDIENTE, MEDIOS DE GENERACION DE SEÑALES DE ENTRADA A LAS FRECUENCIAS DE CAMPO Y LINEA, CON UN CIRCUITO LC ACOPLADO AL ARROLLAMIENTO Y CON UN AMPLIFICADOR DE CONMUTACION AL QUE SE ACOPLE UN CIRUITO DE CONTROL. EL CIRCUITO LC, RESONANTE, SE EXCITA A LA FRECUENCIA DE LINEA PARA MODULAR LA CORRIENTE DE DEFLEXION DE CAMPO. EL CONDENSADOR DE ESTE CIRCUITO SE ACOPLA AL PRIMER ARROLLAMIENTO DE UN TRANSFORMADOR, DEL QUE EL SEGUNDO SE ACOPLA AL AMPLIFICADOR DE CONMUTACION. LA INDUCTANCIA DEL TRANSFORMADOR ES AJUSTABLE CON EL FIN DE CONTROLAR LA FASE DE MODULACION A LA FRECUENCIA DE LINEA DE LA CORRIENTE DE DEFLEXION DE CAMPO. GENERALMENTE, LA SEÑAL DE ENTRADA DE LA FRECUENCIA DE CAMPO ES DE FORMA EN DIENTE DE SIERRA. DE APLICACION PARA PANTALLAS DE VIDEO CON FORMA NO ESFERICA.
