Abstract

CIRCUITO DE BARRIDO VERTICAL ALIMENTADO POR LOS IMPULSOS DE RETORNO DE LINEA OBTENIDOS EN LOS BORNES DEL DESVIADOR HORIZONTAL. LOS IMPULSOS DE RETORNO DE LINEA SE RECOGEN POR UN TRANSFORMADOR (TL) Y SE SUMINISTRAN A UN GENERADOR (2), QUE PERMITE CORRIENTE BIDIRECCIONAL Y TENSION MONODIRECCIONAL, CONTROLADO EN LA PUERTA DE UN TIRISTOR (TH1) POR UN CIRCUITO DE MANDO (3). EL GENERADOR (2) ALIMENTA UNA CARGA (1) QUE CONTIENE AL DESVIADOR VERTICAL (DU) Y UN CONDENSADOR (CL) DE SUFICIENTE CAPACIDAD PARA MANTENER SIEMPRE TENSION POSITIVA EN LOS BORNES DE LA CARGA. EL CIRCUITO DE MANDO (3) ACTUA SEGUN LAS SEÑALES QUE RECIBE DE UN GENERADOR DE DIENTES DE SIERRA (5), LOS IMPULSOS A LA FRECUENCIA DE LINEA (4) Y LA TENSION DEL CONDENSADOR (CL). EN UN BORNE (A) DEL SECUNDARIO (S1) SE PUEDE CONECTAR UN RECTIFICADOR (D2, C2) PARA ALIMENTACION DE VIDEO.
