Claim 20:
21. An apparatus comprising:
a power converter having a multi-layer printed circuit board (“PCB”) including a first conductive layer, a second conductive layer, and an insulation layer separating the first and second conductive layers;
a magnetically permeable core structure including a number, Np, of magnetic paths, each passing through the first and second conductive layers in at least two leg locations;
a number, X, of first windings each including a respective first winding element that passes through a respective subset of the magnetic paths between the respective leg locations, each respective subset including a respective number, Npx, of the magnetic paths, at least one of the first winding elements being formed in the first conductive layer of the PCB;
a plurality of second winding elements, each passing through a respective subset of the magnetic paths between the respective leg locations, each subset including a number, Ns, of the magnetic paths, the second winding elements being formed in the second conductive layer;
a plurality of cell elements each including a switch and a capacitor, in which each cell element is associated with and includes at least a portion of a respective second winding element;
wherein the respective second winding element associated with each cell element has a first end connected to a terminal of the switch in the cell element and a second end connected to an output terminal in a neighboring cell element, and the second winding elements in neighboring cell elements step through the respective subsets of magnetic paths in the same direction; and
wherein the cell elements are arranged in two or more groups, each group connected to support a respective converter output.
