Abstract

A pot core matrix transformer has a large number of connections from its secondary winding, the connections being fairly evenly distributed around the bottom surface. If these connections are terminated in a circuit board which has been optimized for good thermal conductivity, the temperature rise in the transformer will be small, even with very high current densities. Embodiments are shown for mounting directly on a heat sink and for surface mounting on a circuit card.
