Abstract
The present invention provides a power transformer having a low profile and low overall volume. The power transformer also has improved isolation between the primary and the secondary windings, while at the same time providing improved electromagnetic coupling between these windings. The power transformer comprises an insulating enclosure for encapsulating a primary winding wound therein. The secondary winding comprises two electrically connected planar windings stamped from a conductive foil sheet. The insulating enclosure is positioned between the two planar windings of the secondary winding. The power transformer also comprises a core for coupling magnetic flux from the primary winding to the secondary winding.
