Abstract
A low profile high current composite transformer is disclosed. Some embodiments of the transformer include a first conductive winding having a first start lead, a first finish lead, a first plurality of winding turns, and a first hollow core; a second conductive winding having a second start lead, a second finish lead, a second plurality of turns, and a second hollow core; and a soft magnetic composite compressed surrounding the first and second windings. The soft magnetic composite with distributed gap provides for a near linear saturation curve.
