A transform-rectifier module has a one-half turn secondary winding installed with very short, direct connections to four rectifiers. The core of the transformer has two parallel through holes. The secondary winding comprises two "Y" shaped windings. The "Y" legs of each winding are installed through the through holes from opposite sides of the core, and the ends of the "Y" windings connect to the four rectifiers. The common connections of the "Y" windings terminate on a ground plane. The rectifiers may be mounted on a common power plane which may also be a heat sink for the rectifiers and a mounting plate for the module as a whole. There is room through the through holes for a primary winding, which may be installed during manufacture or later. The modules may be used singly or in a matrix transformer-like arrangement. They are characterized by very low leakage inductance, high current capacity, good thermal properties and a low profile.
