Abstract
A coupled inductor array has length, width, and height. The coupled inductor array includes a monolithic magnetic core formed of a magnetic material having a distributed gap, and a plurality of windings embedded in the monolithic magnetic core. Each winding forms a respective winding loop of one or more turns around a respective winding axis, and each winding axis extends in the height direction. Areas of the monolithic magnetic core enclosed by the winding loops are greater than areas of the monolithic magnetic core outside of the winding loops, as seen when the coupled inductor array is viewed cross-sectionally in the height direction. One possible application of the coupled inductor array is in a multi-phase switching power converter.
