Abstract

EN UN CIRCUITO DESVIADOR TAL COMO PARA UN DISPOSITIVO DE REPRESENTACION VISUAL CRT, LA CORRIENTE MODULADA QUE SE GENERA EN UN CIRCUITO DE CONTROL DE RED EN ESPECIAL PARA LA CORRECCION DE DISTORSION DE IMAGEN POR LADOS CURVADOS DE ESTE-OESTE, SE ACOPLA A UNA ETAPA DE SALIDA DE UN CIRCUITO DESVIADOR (100) VIA UN AMPLIFICADOR (Q2) ACCIONADO DE CLASE A QUE SIRVE COMO FUENTE DE CORRIENTE CON UNA ALTA IMPEDANCIA DE SALIDA DURANTE EL RETROCESO DEL PUNTO. LA FUENTE DE CORRIENTE PREVIENE EL ACOPLAMIENTO DE UNA SEÑAL A UNA FRECUENCIA DE RETROCESO DURANTE EL RETROCESO DEL PUNTO ENTRE UNA BOBINA DE ALTO VOLTAJE (W1) DEL TRANSFORMADOR DE BARRIDO (T1) Y UN CIRCUITO RESONANTE DE RETROCESO (27) QUE INCLUYE UN BOBINADO DESVIADOR (LH). LA ALTA IMPEDANCIA DE SALIDA DEL AMPLIFICADOR FUENTE DE CORRIENTE DURANTE EL RETROCESO MANTIENE EL VALOR MEDIO DE LA CORRIENTE MODULADA DURANTE EL RETROCESO SIN VERSE AFECTADO POR LA AMPLITUD DEL VOLTAJE DE RETROCESO QUE SE DESARROLLA EN EL CIRCUITO RESONANTE DE RETROCESO (27). DE ESTA FORMA, LA VARIACION DE LA CARGA DEL VOLTAJE DEL ELECTRODO SE PREVIENE DE QUE SE PRODUZCA LAS DISTORSIONES DE "DIENTES DE RATON".
