Transformer

A transformer comprises first winding portions (101, 102) constituting a first foil winding and second winding portions (103, 104) constituting a second foil winding having a substantially same magnetic axis as the first foil winding. The first and second winding portions are interleaved in directio...

Summary:A transformer comprises first winding portions (101, 102) constituting a first foil winding and second winding portions (103, 104) constituting a second foil winding having a substantially same magnetic axis as the first foil winding. The first and second winding portions are interleaved in directions substantially perpendicular to the magnetic axis so as to reduce the leakage inductances of the first and second foil windings. The first winding portions are electrically interconnected so that at least one end-portion of each first winding portion is split to constitute two strips (105a, 105b) folded to mutually opposite directions substantially parallel with the magnetic axis, and ends of the strips of different first winding portions are interconnected to constitute connection bridges over a particular one of the second winding portions located between these first winding portions. The second winding portions are electrically interconnected in the corresponding way to constitute the second foil winding.
