The present invention describes a planar transformer having a plurality of juxtaposed magnetic cores as well as a two-layer printed circuit board for spiralling a plurality of windings. Each arm of a plurality of juxtaposed magnetic cores respectively goes through a corresponding hole in the middle of these windings, to magnetically couple the current in the main winding to the other windings.
