Abstract: An example transformer cell includes a printed circuit board (PCB) having a plurality of layers and at least two transformers. The at least two transformers include a primary winding implemented in a plurality of primary layers among the plurality of layers, a plurality of secondary windings implemented in a plurality of secondary layers among the plurality of layers, and a core extending through the primary winding and the plurality of secondary windings. The transformer cell further includes a first output capacitor located above a top layer among the plurality of layers and along a first edge of the PCB, a second output capacitor located above the top layer along a second edge of the PCB, the second edge being opposite the first edge. The transformer cell additionally includes one or more switching devices located between the first and the second output capacitors.
