Abstract
A high-frequency transformer includes a plurality of cores having a central leg, the cores being arranged to form core windows that are separated by the central legs. A primary winding has a predetermined length of electrically conductive wire that is wound about the central legs and extends through each of the core windows. One or more secondary windings extend through each core window, generally adjacent to the primary winding. The core windows are sized and shaped to provide a predetermined amount of leakage inductance between the primary and secondary windings, and are further adapted to provide a path for cooling air through an interior portion of the transformer.
