Abstract

This article describes an inductor and a transformer, each made from plate-like elements coupled to form high current windings in each case forming a compact structure having a flat surface for thermal contact to a heat sink. Fig. 1 shows an inductor made from a series of copper plate elements 10a-10h and end L-shaped copper plate elements 12 and 14, interspaced by electrical insulating sheet elements 16a-16i and conductive washer-like elements 18a-18i. Fig. 2 shows an exploded view of an series of these elements to illustrate their mode of connection to form, in effect, an electrically conductive helix. The arrows 20 indicate direction of electric current in the plate elements, and the arrows 22 indicate the electric current through the bridging washer-like elements between them.
