Abstract
In some embodiments, a configurable multiphase coupled magnetic structure may include a four-sided pot core defining an interior space, one or more cylindrical cores disposed within the interior space of the four-sided pot core, and at least two windings respectively wound around the one or more cylindrical cores, wherein the at least two windings are connected in a multiphase power delivery configuration. The windings may be multi-turn windings. The four-sided pot core may be a rectangular-shaped pot core. The cylindrical cores may be I-cores. Other embodiments are disclosed and claimed.
