Abstract
EL INVENTO SE REFIERE A UN APARATO ACOPLADOR PARA UNA LAMPARA DE DESTELLO QUE DEBE MEJORARSE EL FUNCIONAMIENTO SEGURO DURANTE EL ENCENDIDO DE LA LAMPARA DE DESTELLO. CON ARREGLO AL INVENTO EL APARATO ACOPLADOR PRESENTA UN MODULADOR (2) UNIDO CON EL TRANSFORMADOR (1) DE TENSION ALTERNA-TENSION CONTINUA YA QUE LA FRECUENCIA DE FUNCIONAMIENTO MODIFICABLE DE LOS TRANSFORMADORES (1) SE MODIFICA PARA EL ENCENDIDO FACTIBLE DE LA LAMPARA DE DESTELLO. A TRAVES DE LA FRECUENCIA DE FUNCIONAMIENTO MODIFICADA DE LOS TRANSFORMADORES (1) SE LOGRA DE FORMA SEGURA LA FRECUENCIA DE RESONANCIA DE UNOS CIRCUITOS DE RESONANCIA EN SERIE QUE SUMINISTRA LA TENSION DE ENCENDIDO CUANDO LAS CARGAS CAPACITIVAS NO SE SINTONIZA CON EL CIRCUITO DE CARGA DE LOS TRANSFORMADORES. EL INVENTO ES APLICABLE PARA EL FUNCIONAMIENTO DE LAMPARAS DE DESTELLO EN VEHICULOS.
