Abstract
Disclosed are transformer-rectifier blocks for power converters. A transformer-rectifier block has a transformer and a rectifier circuit that are vertically integrated with a substrate. The transformer has a magnetic core, primary windings that have one or more turns, and secondary windings that are wound a single turn over corresponding primary windings. The transformer is mounted on one side of the substrate, and the rectifier circuit is mounted on an opposing side of the substrate.

A transformer-rectifier block for a power converter, the transformer-rectifier block comprising:
- a substrate having a first side and a second side;
- a transformer having a bottom end that is mounted on the first side of the substrate, the transformer comprising a magnetic core, a first primary winding, a first secondary winding that is wound over the first primary winding, a second primary winding, and a second secondary winding that is wound over the second primary winding, each of the first and second primary windings has one or more turns, and each of the first and second secondary winding is wound a single turn;
- and
- a rectifier circuit that is mounted on the second side of the substrate, the rectifier circuit comprising a first rectifier that is electrically connected to an end of the first secondary winding through the substrate and a second rectifier that is electrically connected to an end of the second secondary winding through the substrate.
A transformer-rectifier block for a power converter, the transformer-rectifier block comprising:
- a substrate;
- a transformer having a bottom end that is mounted on a first side of the substrate, the transformer comprising a magnetic core, a first primary winding that has one or more turns, a first secondary winding that is wound over the first primary winding a single turn, a second primary winding that has one or more turns and is electrically connected in series with the first primary winding, and a second secondary winding that is electrically connected in series with the first secondary winding and is wound over the second primary winding a single turn;
- a first rectifier that is mounted on a second side of the substrate and is electrically connected to an end of the first secondary winding by way of a first connection point on the bottom end of the transformer;
- and
- a second rectifier that is mounted on the second side of the substrate and is electrically connected to an end of the second secondary winding by way of a second connection point on the bottom end of the transformer,
