Nucleo de Polvo de Hierro

Núcleos polvo de hierro

Los espacios de aire dentro del núcleo hacen que el valor de corriente que fluye a través de la bobina sea mucho más alto que en el caso de los núcleos de ferrita y no provocan una saturación magnética rápida. Los núcleos de polvo se caracterizan por una capacidad excepcional para almacenar energía. Además, no emiten ruidos ni perturbaciones acústicas que pueden ocurrir en los componentes donde se aplicaron los núcleos de ferrita con huecos.

Los núcleos están hechos de varios materiales en polvo de hierro. Cada material tiene un código único con diferentes colores de recubrimiento, que identifica fácilmente el magnetismo. Los diversos materiales difieren en permeabilidad, rango de frecuencia, curva de magnetización, pérdida de potencia, etc. Debido a sus propiedades, los núcleos de polvo de hierro son materiales magnéticos relativamente económicos para la producción de varios choques en sistemas de potencia y EMI.

Los componentes típicos fabricados a base de núcleos de polvo de hierro se utilizan en reactancias de salida de CC, reactancias PFC y bobinas para eliminar el método diferencial de interferencia.

La desventaja son las grandes pérdidas de potencia generadas en los núcleos de hierro, por lo que no se utilizan con tanta frecuencia en los transformadores de pulsos.

Los núcleos de polvo de hierro se producen principalmente como núcleos toroidales, pero también están disponibles en forma de E, U y núcleos cilíndricos.
