ABSTRACT:
Compound inductors for use in switching regulators have two or more symmetrically coupled windings so the component size is reduced as well as a reduction in power losses compared with conventional inductors. The compound inductors may be used in buck and boost regulators. The compound inductor assembly has a first inductor with a first winding on a first magnetic core, a second inductor with a second magnetic core outside the first winding of the first inductor, and a second winding around the first winding of the first inductor and the second core. One end of the first winding and the corresponding end of the second winding is connected to a common connection such that voltages from an alternating current flowing in the first winding have the same polarity in the first winding and in the second winding.
