Abstract

A magnetic element includes a magnetic core and a winding. The magnetic core includes a first and second magnetic cover disposed oppositely, and at least one first magnetic column, at least one second magnetic column and at least one common magnetic column disposed between the first and second magnetic covers. The winding includes at least one first winding wound around at least one first magnetic column, and at least one second winding wound around at least one said second magnetic column. A first differential mode inductor is formed with the first winding, the first magnetic column, the first magnetic cover, the common magnetic column and the second magnetic cover. A power inductor or a power transformer is formed with the second winding, the second magnetic column, the first magnetic cover, the common magnetic column and the second magnetic cover.
