Abstract

ESTAS TENSIONES A MENUDO SON NECESARIAS PARA PRODUCIR CORRIENTES DE CORRECCION, QUE DEBEN SER IGUALES EN FASES CON LA ONDA BASE DE OTRA TENSION. SE CONOCE EL USO DE OTRA CONEXION DE OSCILADOR DE FILTRO O SINCRONIZADA, PERO QUE HACE NECESARIA LA NIVELACION EN LA ONDA BASE DE OTRA TENSION. SE CONOCE EL USO DE UNA CONEXION DE OSCILADOR DE FILTRO O SINCRONIZADA, PERO QUE HACE NECESARIA LA NIVELACION EN LA ONDA BASE, PARA LO QUE ES NECESARIO UNA CONEXION ADICIONAL, SOBRE TODO SI LA TENSION ESTA SINTONIZADA CON VARIAS FRECUENCIAS. EL INVENTO MUESTRA UN PROCEDIMIENTO CON EL MINIMO DE CONEXIONES Y UN GRAN MARGEN DE VARIACION DE FRECUENCIAS. DOS TENSIONES CONTRAFASICAS CON EL MISMO VALOR PUNTA Y DESARROLLO DE LA CURVA EN FORMA DE SIERRA, SE SUMAN, PRESENTANDO UNA DE LAS TENSIONES CON SURVA DE SIERRA UNA CURVA DE DESARROLLO HORIZONTAL DURANTE CIERTOS TRAMOS TEMPORALES DEL PERIODO T. PRODUCCION DE UNA CORRIENTE DE CORRECCION PARA CONEXIONES VERTICALES DE DISTRIBUCION EN RECEPTORES DE TELEVISION.
