Abstract

Perfeccionamientos en vibradores de transistores para el abastecimiento de tensión a lámparas fluorescentes, cuyo transformador vibrador contiene devanados secundarios para la tensión alterna de caldeo, la tensión alterna de trabajo y la tensión alterna auxiliar de encendido, caracterizados porque el vibrador está provisto de medios de maniobra estáticos a través de los cuales tiene lugar, después de cada conexión de la tensión contínua de abastecimiento, una entrega cronológicamente retardada de la tensión alterna de trabajo con respecto a la tensión alterna de caldeo.
