Abstract

DISPOSITIVO CEBADOR ELECTRONICO PARA TUBO FLUORESCENTE. COMPRENDE UN CIRCUITO TEMPORIZADOR, QUE COOPERA CON UN CIRCUITO DE SOBRETENSION Y UN CIRCUITO DE PRECALENTAMIENTO, UNIDO POR SUS DOS PUNTOS DE CONEXION (A, B) A LOS FILAMENTOS (F1, F2) DEL TUBO (1). EL CIRCUITO DE SOBRETENSION, CONSTITUIDO POR UN CONDENSADOR (C2), UNAS RESISTENCIAS (R6, R7), UN DIODO (D1), UN TIRISTOR (TH) Y UN AUTOTRANSFORMADOR (T1), Y EL CIRCUITO DE PRECALENTAMIENTO, CONSTITUIDO POR UNA RESISTENCIA (R8), UN DIODO (D2), UN TIRISTOR (TH), UN ARROLLAMIENTO SECUNDARIO (S) Y UN ELEMENTO DE PROTECCION (5), DISPONEN DE UN ORGANO DE CONMUTACION COMUN CONSTITUIDO POR EL TIRISTOR (TH). EL CIRCUITO TEMPORIZADOR, QUE DESARROLLA UNA TENSION PROGRESIVAMENTE CRECIENTE, ESTA CONSTITUIDO ESENCIALMENTE POR UN CONDENSADOR (C1), UNA RESISTENCIA (R5) Y UN DIODO (D3) Y ACTUA SOBRE EL TIRISTOR (TH) POR MEDIO DE UNAS RESISTENCIAS (R1, R8), EN EL CASO DEL PRIMER CIRCUITO, Y DE UNAS RESISTENCIAS (R2, R8) ASOCIADAS A UN ELEMENTO REGULADOR DE LA TENSION EN SUS BORNES, DIODO ZENER (D4), PARA EL SEGUNDO CIRCUITO.
