ABSTRACT:
An easy to assemble transformer for use in an electronics module of an electric vehicle. The transformer can be assembled from the "top down," thus alleviating the need to build the transformer as a subassembly unit. During manufacture of the transformer, windings are wound onto a thermally conductive coil form. Next upper and lower E-shaped core members are inserted into openings in the top and bottom of the form so that the side legs and the center legs of the E's touch and are in alignment. The thermally conductive coil form has a portion that touches a cold plate when the transformer is mounted on the cold plate. The transformer is further secured to the cold plate by a mounting bracket.
