Abstract
UN CIRCUITO DE ATENUACION A TRAVES DE UNA DERIVACION PARCIAL REACTIVA CON REACTANCIA PARA LAMPARAS DE DESCARGA DE GAS. CONSTA DE UN CONVERTIDOR DE FRECUENCIA, SIENDO EL CONVERTIDOR OPERADO POR UNA ONDA RECTANGULAR DE AMPLITUD UNIFORME A LAS MISMA FRECUENCIA QUE LA FRECUENCIA APLICADA DEL VOLTAJE DE CONTROL, UNA ETAPA INICIAL DE FILTRACION SEPARA LA SEÑAL DE CONTROL DE ALTA FRECUENCIA DE LOS COMPONONTES DE LINEA Y OTRAS DE MAS BAJA FECUENCIA DE LOS COMPONENTES DE LINEA Y OTRAS DE MAS BAJA FRECUENCIA, UN AMPLIFICADOR DE ALTA GANANCIA Y UN CIRCUITO LIMITADOR PROPORCIONAN LA ONDA RECTANGULAR. EL VOLTAJE PROPORCIONAL A LA FRECUENCIA DE CONTROL SE DESARROLLA CON PREFERENCIA EN UN CIRCUITO DOBLADOR DE VOLTAJE Y SE APLICA A UN SINCRONIZACION, UN CIRCUITO RC DELANTE DEL CONVERTIDOR DE FRECUENCIA ASEGURA QUE LAS SEÑALES FUERA DEL MARGEN DE CONTROL CARECEN DE EFECTO SOBRE LA SEÑAL DE CONTROL.
