Abstract

EL CIRCUITO CONSTA DE UN CAPACITOR (CO) QUE SE DESCARGA Y CARGA ALTERNATIVAMENTE EN SINCRONISMO CON LA SEÑAL QUE SE DESARROLLA A TRAVES DE LOS TERMINALES DE UNA RESISTENCIA (9) QUE FUNCIONA PARA DETECTAR LA CORRIENTE EN LA LAMPARA (L). DE ESTE MODO SE OBTIENE UNA FORMA DE ONDA EN DIENTE DE SIERRA (D), QUE SE COMPARA CON UN NIVEL UMBRAL (SA) QUE VARIA DEPENDIENDO DE LA CORRIENTE QUE SE HA DE SUMINISTRAR A LA LAMPARA (L). EN BASE A ESTA COMPARACION SE PRODUCEN UNAS SEÑALES LOGICAS (J, K) QUE SE UTILIZAN PARA CONTROLAR A LOS CONMUTADORES DE POTENCIA (3A, 3B) DEL INVERSOR (1) QUE CONTROLA LA LAMPARA (L).
