Abstract
UN CIRCUITO DE MANEJO DE LAMPARAS DE DESCARGA DE GASES (102, 104, 106) QUE TIENE FILAMENTOS CALENTABLES (102A&B, 104A&B, 106A&B) INCLUYE: UN OSCILADOR RESONANTE EN SERIE AUTOOSCILANTE (196, 198, 178, 180) QUE PRODUCE UNA TENSION DE SALIDA DE ALTA FRECUENCIA PARA APLICAR A LAS LAMPARAS; UN DIVISOR RESISTIVOCAPACITIVO (190, 192) PARA INICIALIZAR EL OSCILADOR DESPUES DE UNA PRIMERA DETENCION; UN IC INDUCTIVO ELEVADOR DEL VOLTAJE (144) PARA PROVOCAR QUE EL OSCILADOR PRODUZCA UNA TENSION DE SALIDA ELEVADA CUANDO EL IC ELEVADOR DE VOLTAJE ESTE ACTIVADO Y UNA TENSION DE SALIDA NO ELEVADA CUANDO NO ESTE ACTIVADO; Y UN DIVISOR RESISTIVO-CAPACITIVO (170,172) PARA INICIALIZAR EL IC ELEVADOR DE VOLTAJE DESPUES DE UNA SEGUNDA DETENCION. LA SEGUNDA DETENCION ES SUSTANCIALMENTE MAS LARGA QUE LA PRIMERA DETENCION. EL VOLTAJE DE SALIDA SIN ELEVAR ES SUFICIENTE PARA CALENTAR EL BOBINADO DEL FILAMENTO, PERO INSUFICIENTE PARA INICIAR EL ENCENDIDO DE LA(S) LAMPARA(S), Y EL VOLTAJE DE SALIDA ELEVADO ES SUFICIENTE PARA INICIAR EL ENCENDIDO DE LA(S) LAMPARA(S). POR LO TANTO, LOS FILAMENTOS SON PRECALENTADOS CON ANTERIORIDAD AL ENCENDIDO EN EL PERIODO DE TIEMPO ENTRE LA PRIMERA Y LA SEGUNDA DETENCIONES.
