Patent ID: 7154196

Claim:
A printed circuit board for a three-phase power device, the printed circuit board having at least a first switching device, a second switching device, a third switching device, and a common source node that are each mounted to a surface of the printed circuit board, the printed circuit board comprising: a first set of conductive paths in a first layer of the printed circuit board that provides electrical conductivity between the common source node, the first switching device, the second switching device, and the third switching device; a second set of conductive paths in a second layer of the printed circuit board that provides electrical conductivity between the common source node, the first switching device, and the third switching device; and a plurality of vias that connect the first layer of the printed circuit board to the second layer of the printed circuit board; wherein a distance between the common source node and the first switching device and a distance between the common source node and the third switching device is greater than a distance between the common source node and the second switching device.
