Abstract

EL CIRCUITO DE SUMINISTRO PARA LAMPARAS DE DESCARGA (L) COMPRENDE UN INVERSOR (3) PARA GENERAR UNA TENSION DE SUMINISTRO EN UNA FRECUENCIA DE CONMUTACION ESPECIFICADA (F C ) PARA UN CIRCUITO DE CARGA (15) QUE COMPRENDE COMO MINIMO UNA LAMPARA (L) Y UN CIRCUITO RESONANTE (23, 25) EN SERIE CON LOS ELECTRODOS (17, 19) DE DICHA LAMPARA. ASOCIADO CON EL CIRCUITO DE CARGA HAY UN CIRCUITO DE CONTROL (41) PARA DESACTIVAR EL SUMINISTRO AL CIRCUITO DE CARGA EN CASO DE FUNCIONAMIENTO DEFECTUOSO DE LA LAMPARA (L). EL CIRCUITO DE CONTROL (41) COMPRENDE UN FILTRO DE PASO DE BANDA (35) CENTRADO EN LA FRECUENCIA DE CONMUTACION (F C ) DEL INVERSOR Y CUYA SEÑAL DE ENTRADA DEPENDE DE LA TENSION EN UN PUNTO (P) DEL CIRCUITO DE CARGA; LA SEÑAL DE SALIDA DEL FILTRO SE ENVIA A MEDIOS DE CONTROL (37, 39) ASOCIADOS A DICHO INVERSOR (3), PARA DESACTIVAR EL SUMINISTRO AL CIRCUITO DE CARGA EN CASO DE FUNCIONAMIENTO DEFECTUOSO.
