Abstract
CIRCUITO DE ESTABILIZACION DE ALTA TENSION PARA UN APARATO DE PRESENTACION DE VIDEO. COMPRENDE UNA ETAPA DE SALIDA DE UN CIRCUITO DE DESVIACION HORIZONTAL (Q1, CR, LSIY SC, W1) QUE GENERA UN IMPULSO DE RETROCESO (VSI2 SC) EN UN ARROLLAMIENTO TERCIARIO (W2) DE UN TRANSFORMADOR DE SALIDA DE LINEA (T1). SE PRODUCE UN IMPULSO DE RETORNO (YSI3 SC), SUSTANCIALMENTE MAS ANCHO QUE EL IMPULSO DE RETROCESO, EN UN ARROLLAMIENTO (WB) DE UN TRANSFORMADOR SECUNDARIO (T2) QUE ESTA ACOPLADO EN SERIE CON EL ARROLLAMIENTO TERCIARIO DE TAL MANERA QUE EL IMPULSO DE RETROCESO SE PRODUCE CUANDO UNA PARTE DE CRESTA DEL IMPULSO DE RETORNO ES YA RELATIVAMENTE PLANA. LA AMPLITUD DEL IMPULSO DE RETORNO SE CONTROLA EN UN BUCLE DE REALIMENTACION NEGATIVA (R63, 104, Q4, Q5, WA) PARA ESTABILIZAR UNA TENSION (U) DE ELECTRODO FINAL. EL INVENTO ES APLICABLE A RECEPTORES Y MONITORES DE TELEVISION.
