    摘要： The magnetic device consists of a planar winding board, which contains the windings for both the inductor and the transformer. Thus, this invention centers on integrating the windings of multiple magnetic devices, not integrating the cores. By connecting the transformer secondary winding directly to the output inductor winding without using any intermediate headers and/or termination pins or conductive copper traces, both electrical path and the termination resistance will be minimized. Furthermore, the number of headers or termination pins required will also be reduced, which helps to not only alleviate the issue associated with co-planarity of the termination pins, but also reduce the cost of the material and manufacturing.

    摘要： For use in a power converter having a rectifier coupled to an output thereof, a snubber circuit including an energy storage device coupled to the rectifier that moderates a voltage across the rectifier and a method of moderating the voltage. In one embodiment, the snubber circuit includes: (1) a first switch that regulates a voltage across the energy storage device, (2) an inductor, coupled to the first switch, that provides a discharge path for energy stored in the energy storage device when the first switch is conducting and (3) a second switch that recovers energy stored in the inductor to the output when the first switch is not conducting. The snubber circuit thereby reduces voltage stress across the rectifier during a current limit mode of operation.
