Abstract

An embodiment of an inductor assembly includes a core, a first conductor, and a second conductor. The core includes first and second members, a first group of one or more forms extending between the members, a second group of one or more forms extending between the members, and an isolating region that magnetically isolates the first group of forms from the second group of forms. The first conductor is wound about a first one of the forms in the first group, and the second conductor is wound about a second one of the forms in the second group. Such an inductor assembly may allow both coupled and uncoupled inductors to be disposed on a common core, thus potentially reducing the cost and size of the inductors as compared to the coupled inductors being disposed on one core and the uncoupled inductors being disposed on another core.
