Abstract

DOS DEVANADOS (W2A, W2B) DE UN TRANSFORMADOR (T1) EN UN CIRCUITO DE DEFLACCION VERTICAL ESTAN ACOPLADAS INDUCTIVAMENTE CON LA POLARIDAD CONTRARIA A UNA FUENTE DE PULSOS DE RETRAZO (12). LOS DEVANADOS TIENEN UNA UNION COMUN CONECTADOS A TIERRA. UN CIRCUITO (L1, C1, L2, C2) ACTIVADO POR LOS PULSOS DE RETRACEO GENERA CORRIENTES MODULADAS DE POLARIDAD OPUESTA . LA CONDUCCION DE CADA CORRIENTE SE CONTROLA POR UN CIRCUITO CONMUTADOR (18, 20) QUE INCLUYE UN INTERRUPTOR SEMICONDUCTOR (Q1, Q2) Y DOS DIODOS (D1-D4). LOS CIRCUITOS INTERRUPTORES ESTAN ACOPLADOS UNO AL OTRO EN LA UNION, Y LA UNION ESTA ACOPLADA A UNA CAPACITANCIA (C3) ALMACEN DE ENERGIA. UNO DE LOS DIODOS CONDUCE PARTES VALORADAS POSITIVAMENTE A LA CORRIENTE RESPECTIVA A TRAVES DE LA CAPACITANCIA DE ALMACEN DE ENERGIA Y EL OTRO DE LOS DIODOS CONDUCE PORCIONES VALORADAS NEGATIVAMENTE DE LA RESPECTIVA CORRIENTE A TRAVES DEL INTERRUPTOR SEMICONDUCTOR. CADA INTERRUPTOR SEMICONDUCTOR ES UN PASO DE CORRIENTE DE DESCARGA. LA CAPACITANCIA DE ALMACEN DE ENERGIA ES RESPONSABLE DE LAS CORRIENTES PARA DESARROLLAR UNA CORRIENTE DE DEFLECCION VERTICAL EN UNA BOBINA DE DESVIACION (LV). LA CORRIENTE DE DEFLECCION VERTICAL ESTA RELACIONADA CON LA DIFERENCIA DE AMPLITUD ENTRE LAS PARTES POSITIVAMENTE VALORADAS DE LA CORRIENTE. UNA CORRIENTE DE CORRECION DE AMORTIGUADOR-PUNTO NORTE-SUR EN FASE CON LA DEFLECCION HORIZONTAL SE GENERA POR INTEGRACION DEL VOLTAJE DE DEFLECCION VERTICAL (V1) EN LA BOBINA DE DESVIACION DE DEFLECCION VERTICAL. UN TRANSFORMADOR DE AMORTIGUADOR-PUNTO (T2) TIENE UN PRIMER DEVANADO LIGADO A LA CAPACITANCIA DE ALMACENAMIENTO DE ENERGIA (C3) Y UN SEGUNDO DEVANADO (W4) FORMA PARTE DE UN CIRCUITO RESONANTE HORIZONTAL ACOPLADO EN SERIE CON LA BOBINA DE DESVIACION DE DEFLACCION VERTICAL (LV) .
