Abstract
A magnetic core is provided. The magnetic core includes a plurality of magnetic core units each having at least one non-shared magnetic core part that is not shared with the neighboring magnetic core unit, wherein a reluctance of the shared magnetic core part is smaller than the reluctance of a non-shared magnetic core part of the magnetic core units, and directions of a direct current magnetic flux in the shared magnetic core part of the neighboring two magnetic core units are opposite.
