Abstract
A transformer with a secondary structure formed in a figure 8 pattern. The secondary structure defines two conducting paths which each incorporate a rectifier and each encircle part of the core only once. The conducting paths overlap and cross only in the window region of the core. The design of the secondary structure allows for the mechanical connections to the transformer to be physically separated on opposite ends of the transformer assembly. This structure allows for alleviation of the connector congestion and provides better cooling and also permits shorter connections to the rectifiers.
