ABSTRACT:
A full wave DC to DC converter that is magnetically integrated so that the function of the output filter inductor is magnetically included in the transformer assembly. Two essentially symmetrical transformers have their primary windings connected in series and are driven by a full wave switched primary circuit such as a full bridge. The transformer secondaries are polarized so that their rectifying diodes conduct on opposite phases, so only one transformer secondary conducts for each half cycle. The conducting secondary winding conducts for each half cycle. The conducting secondary winding conducts both forward current reflected from the primary and flyback current from collapsing core flux. The transformer having the non-conducting secondary stores energy as magnetic flux. On the other half-cycle, the transformers reverse roles. Because stored transformer flux energy is released to the load through the secondary windings, continuous current is maintained and no separate output smoothing inductor is required.
