Abstract

RED DE CONEXION, ESPECIALMENTE PARA UN RECEPTOR DE TELEVISION, CON UN TRANSITOR DE MANIOBRA QUE CONECTA Y DESCONECTA PERIODICAMENTE LA CORRIENTE EN EL ARROLLAMIENTO PRIMARIO Y CON UNA CONEXION PROTECTORA PARA LA LIMITACION DE LA CORRIENTE PRIMARIA.CARACTERIZADA PORQUE UNA TENSION DE REFERENCIA PROPORCIONAL A LA CORRIENTE PRIMARIA, ESTA APLICADA, A TRAVES DE UN ELEMENTO DE UMBRAL, AL ELECTRODO DE MANIOBRA DE UN TIRISTOR, QUE ESTA SITUADO ENTRE LA BASE DEL TRANSITOR DE MANIOBRA Y UN PUNTO CON UNA TENSION DE BLOQUEO PARA EL TRANSITOR; Y PORQUE LOS DOS EXTREMOS DE UNA RESISTENCIA MEDIDORA DE CORRIENTE ESTAN CONECTADOS AL EXTREMO DEL TIRISTOR ALEJADO DE LA BASE DEL TRANSITOR DE MANIOBRA.
