Abstract
In an output stage for switching regulated power supply, including a step down transformer and a full wave rectifier, significantly increased power output and a small, compact size are achieved by reducing the length of the path through which electrical power must flow in the power supply, by symmetrically arranging all electrical paths within the power supply, and by utilizing single turn windings, each associated with a diode rectifier element. Two groups of diodes are respectively mounted on two heat sinks which are arranged in parallel co-planar relationship under a circuit board on which the transformer is mounted. In a first embodiment, the first group of diodes is forwardly mounted on the heat sink, that is, with their anodes exposed, while the other diodes are reversely mounted on the other heat sink. In a second embodiment, all diodes are forwardly mounted on the heat sinks. The single turn secondary windings are connected to the diodes at interfaces symmetrically positioned around the periphery of the core of the transformer.
