Abstract
EN UNA PIEZA DE LA RED DE CONEXION SE EXPONE, EN CASOS DE ALTERACIONES, COMO SOBRECARGA Y DEFICIENCIA DE LOS COMPONENTES DEL TRANSFORMADOR (TR) Y DE UN TRANSISTOR DE CONEXION (T1) DIRIGIDO PERIODICAMENTE CON UNA FRECUENCIA DE TRABAJO. HAY QUE CREAR UNA PROTECCION. UNA TENSION REGULADORA (UR), QUE SE OBTIENE A TRAVES DE LA RECTIFICACION DE LA TENSION DE IMPULSO EN EL TRANSFORMADOR (TR), MODIFICA LA FRECUENCIA DE TRABAJO DE TAL MANERA, QUE ESTE SE DECRECE CON TENSION REGULADORA (UR) DECRECIENTE. PIEZA ESPECIAL DE LA RED DE CONEXION PARA RECEPTORES DE TELEVISION, GRABADORAS DE VIDEO, Y ORDENADORES PERSONALES.
