Claim 39:
40. 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;
one or more smart dual switching (“SDS”) devices, each including SDS circuitry in an SDS package constructed and arranged as a self-contained electronic switching device, the SDS package having a common terminal, a first switched terminal, and a second switched terminal;
the SDS circuitry including:
a first electronic switch having a first control terminal, a first switched terminal, and a first common terminal,
a second electronic switch having a second control terminal, a second switched terminal, and a second common terminal,
a first SDS control circuit having an input connected to the first switched terminal, an input connected to the second switched terminal, and an output connected to the first control terminal, the first SDS control circuit being constructed and arranged to turn the first switch: (i) OFF while the second switch is ON; and (ii) ON for as long as the second switch is OFF and a voltage across the first switched terminal and the common terminal satisfies predetermined magnitude and polarity thresholds; and
a second SDS control circuit having an input connected to the first switched terminal, an input connected to the second switched terminal, and an output connected to the second control terminal, the second SDS control circuit being constructed and arranged to turn the second switch: (i) OFF while the first switch is ON, and (ii) ON for as long as the first switch is OFF and a voltage across the second switched terminal and the common terminal satisfies predetermined magnitude and polarity thresholds; and

a plurality of cell elements, each cell element including a respective second winding element having a first end connected to a respective switched terminal of a respective SDS and a second end connected to an output terminal and a capacitor.
