Abstract
A switching power converter includes a first and second switching device, an air core coupled inductor, and a controller. The air core coupled inductor includes a first winding electrically coupled to the first switching device and a second winding electrically coupled to the second switching device. The first and second windings are magnetically coupled. The controller is operable to cause the first and second switching devices to repeatedly switch between their conductive and non-conductive states at a frequency of at least 100 kilohertz to cause current through the first and second windings to repeatedly cycle, thereby providing power to an output port. The switching power converter may have a topology including, but not limited to, a buck converter topology, a boost converter topology, and a buck-boost converter topology.
