Abstract
SE PRESENTA UN CIRCUITO (500) PARA CONTROLAR LAMPARAS DE DESCARGA DE GAS CONECTADAS EN SERIE A PARTIR DE UNA BOBINA TRANSFORMADORA SECUNDARIA (528) CONECTADA EN UN PRIMER (529A) Y UN SEGUNDO (529B) PUNTOS RESPECTIVAMENTE CON UN PRIMER (508) Y UN SEGUNDO (514) TERMINALES DE SALIDA A LO LARGO DE LAS LAMPARAS. UN CONDENSADOR (532) ACOPLA EL PRIMER PUNTO A UN TERMINAL DE SALIDA INTERMEDIO (512). LA TENSION DE PREDESCARGA PRODUCIDA A TRAVES DE LA BOBINA SECUNDARIA SE APLICA A TRAVES DE UNA LAMPARA SIMPLE (506) PARA PROVOCAR SU ENCENDIDO. DESPUES DE SU ENCENDIDO, SE LIMITA LA CORRIENTE DEL TERMINAL DE SALIDA INTERMEDIO (512) MEDIANTE UN CONDENSADOR (532), Y LAS LAMPARAS SON ALIMENTADAS EN SERIE. DE ESTA FORMA, EL VOLTAJE QUE SE NECESITA PRODUCIR A LO LARGO DE LA BOBINA SECUNDARIA Y QUE ASEGURA EL ENCENDIDO DE TODAS LAS LAMPARAS, PUEDE REDUCIRSE. ALTERNATIVAMENTE, LOS TERMINALES DE SALIDA A TRAVES DE LAS LAMPARAS PUEDEN CONECTARSE A PUNTOS SOBRE LA BOBINA SECUNDARIA A PARTE DEL PRIMER Y SEGUNDO PUNTO (FIG. 6) O EN MEDIO DEL PRIMER Y SEGUNDO PUNTOS (FIG. 1-4).
