Abstract
UN CIRCUITO DE BOBINA DE INDUCCION QUE TIENE UN INDUCTOR EN SERIE (L7) Y UN CONDENSADOR (C10) EN EL QUE LA CARGA DE LAMPARA (LL) SE CONECTA EN PARALELO CON EL CONDENSADOR. DURANTE LA PREIGNICION DE LA CARGA DE LAMPARA, LA SEÑAL DE ACCIONAMIENTO EMITIDA POR UN INVENTOR QUE GENERA UNA SEÑAL SUSTANCIALMENTE RECTANGULAR COMPRENDE UNA FRECUENCIA FUNDAMENTAL F1. LA FRECUENCIA RESONANTE F0 DEL CIRCUITO L-C CONECTADO EN SERIE ES AL MENOS 2 VECES MAYOR QUE LA FRECUENCIA FUNDAMENTAL F1 PERO INFERIOR AL TERCER ARMONICO DE LA SEÑAL DE ACCIONAMIENTO.
