Transformer-rectifier blocks for power converters

A transformer-rectifier block for a power converter, the transformer-rectifier block comprising:

• a substrate;
• a rectifier module that is disposed on the substrate, the rectifier module comprising an integrated circuit (IC) die that has a first rectifier and a second rectifier;
• and
• a transformer module that is disposed in vertical fashion on top of the rectifier module, the transformer module comprising a transformer with a magnetic core, a first primary winding and a second primary winding of the transformer are connected in series, a first end of a first secondary winding of the transformer is connected to the first rectifier, a second end of the first secondary winding is connected to a first end of a second secondary winding of the transformer, a second end of the second secondary winding is connected to the second rectifier, the first primary winding has one or more turns, the first secondary winding has a single turn and is wound over the first primary winding, the second primary winding has one or more of turns, the second secondary winding has a single turn and is wound over the second primary winding, and the first primary winding and the second primary winding are connected in series.
