Abstract
An output stage for a switching regulated power supply including a step down toroidal core transformer and a full wave rectifier having a significantly increased power output and a small size. The increased power output and small size are achieved by reducing the length of the path through which electrical power must flow in the power supply, by a symmetrical arrangement of all electrical paths within the power supply, and by utilizing single turn secondary windings, each associated with a diode rectifier element. A first group of diodes are mounted on one heat sink and the other diodes are mounted on another heat sink, the two heat sinks being arranged in parallel coplanar relationship under a circuit board mounting the transformer. The single turn secondary windings are connected to the diodes at interfaces uniformly symmetrically positioned along the circumference of a circle concentric with and surrounding the toroidal core.
