Abstract

SE EXPONE UN PROCEDIMIENTO PARA DETERMINAR LA FRECUENCIA DE RESONANCIA DE UN CIRCUITO ELECTRICO RESONANTE, ESPECIALMENTE DE UN CIRCUITO RESONANTE DE ARRANQUE PARA LAMPARAS DE DESCARGA DE GAS A ALTA PRESION, CARACTERIZADO PORQUE EL CIRCUITO RESONANTE SE EXCITA CON DIVERSA FRECUENCIA. LA BUSQUEDA DE FRECUENCIA SE REALIZA EN UNA PASADA DE BUSQUEDA CON ENSAYOS INDIVIDUALES DE MUESTREO, EN LOS QUE SE USA UNA FRECUENCIA AJUSTADA E INVARIABLE. CADA FRECUENCIA INVARIABLE SE SELECCIONA Y USA DE ACUERDO CON UN DETERMINADO ESQUEMA DE BUSQUEDA. EL PRIMER ENSAYO DE MUESTREO SE REALIZA CON UNA FRECUENCIA MEDIA (F MITT ), DE MANERA QUE LA FRECUENCIA MEDIA DEL VALOR MEDIANO SEA LA MINIMA (F MIN ) Y MAXIMA (F MAX ) FRECUENCIA DE RESONANCIA POSIBLE. LA FRECUENCIA DE ENSAYO SE MODIFICA EN ETAPAS (+-N* DL F) PARA CADA ENSAYO SUBSIGUIENTE DE MUESTREO. LA FRECUENCIA DE RESONANCIA HALLADA EN UNA PASADA DE BUSQUEDA SE PUEDE ALMACENAR O RENOVARSE OPTATIVAMENTE COMO FRECUENCIA DE APRENDIZAJE (F LEM ) PARA USO COMO FRECUENCIA DE ARRANQUE EN PASADAS POSTERIORES DE BUSQUEDA. EN UNA REALIZACION VENTAJOSA PROPORCIONADA POR LA INVENCION, LA BUSQUEDA DE FRECUENCIA SE REALIZA CON EL USO DE UNA TENSION, QUE SE ENCUENTRA POR DEBAJO DE LA TENSION DE ARRANQUE, LA CORRIENTE SE MIDE EN EL CIRCUITO RESONANTE, SE DETERMINA EL VALOR MAXIMO DE LA CORRIENTE MEDIDA Y SE INDICA LA FRECUENCIA DE RESONANCIA QUE OCURRE A LA CORRIENTE MAXIMA.
