Abstract

UN RECEPTOR DE TELEVISION DE PROYECCION TIENE UN TUBO DE RAYOS CATODICOS (24) CON UN CAÑON ELECTRONICO PARA EMITIR UN HAZ ELECTRONICO INCIDENTE SOBRE UNA PANTALLA (22), UN YUGO DE DESVIACION ELECTROMAGNETICO (L1, L2, L3) Y UNA BOBINA DE ENFOQUE ELECTROMAGNETICA (L4, L5, L6, L7, L8, L9). UN CIRCUITO EXCITADOR DE LA DESVIACION HORIZONTAL (Q1) SE ACOPLA A UNA BOBINA DE DESVIACION HORIZONTAL (L4, L5, L6) Y PROPORCIONA UNA CORRIENTE DE DESVIACION (IH) A LA BOBINA DE DESVIACION HORIZONTAL PARA LA EXPLORACION DEL HAZ DE MANERA REPETITIVA SOBRE LA PANTALLA. LA BOBINA DE ENFOQUE ES EXCITADA DESDE UN TRANSFORMADOR REDUCTOR DE LA CORRIENTE (X2) QUE TIENE UN DEVANADO PRIMARIO (W1) ACOPLADO EN SERIE CON LA BOBINA DE DESVIACION HORIZONTAL. HAY UN DEVANADO SECUNDARIO (W2) DEL TRANSFORMADOR ACOPLADO A LA BOBINA DE ENFOQUE PARA EXCITAR A LA BOBINA DE ENFOQUE CON UNA CORRIENTE PARABOLICA DE RATIO HORIZONTAL (IF). HAY ACOPLADO EN PARALELO UN CIRCUITO DE CAPACITANCIA Y RESISTENCIA (C1, R1) A LA BOBINA DE ENFOQUE Y AL DEVANADO SECUNDARIO DEL TRANSFORMADOR PARA AJUSTAR UNA RELACION DE FASE DE LA CORRIENTE PARABOLICA RELATIVA A LA CORRIENTE DE DESVIACION HORIZONTAL Y PARA AJUSTAR LA AMPLITUD DE LA CORRIENTE PARABOLICA.
