    Abstract: A method for manufacturing a ferromagnetic-dielectric composite material comprises: (a) placing patterned ferromagnetic layer regions, in a patterning substrate assembly that includes a patterning substrate and a first dielectric layer, in physical contact with a second dielectric layer, the second dielectric layer in a receiving substrate assembly that includes a receiving substrate, (b) forming a bond between the patterned ferromagnetic layer regions and the second dielectric layer; (c) releasing the patterning substrate from the patterning substrate assembly to transfer the patterned ferromagnetic layer regions and the first dielectric layer from the patterning substrate assembly to the receiving substrate assembly; and (d) releasing the receiving substrate from the receiving substrate assembly to form the ferromagnetic-dielectric composite material.

    Abstract: A power converter includes a primary circuit and a secondary circuit. The primary circuit includes two primary LC circuits that are in parallel electrically with each other. A first node of each primary LC circuit is electrically coupled to a high-voltage input. A second node of each primary LC circuit is coupled to a respective terminal of a primary inductor that forms a transformer with a secondary inductor in the secondary circuit. Each primary LC circuit is electrically coupled to a primary switch that operates at approximately the resonance frequency of the primary LC circuits to output an alternating current that passes through the primary inductor. The terminals of the secondary inductor are coupled to respective secondary switches. The switches operate at the resonance frequency of the primary LC circuit to rectify the power. A low-pass filter outputs the mean of the received voltage.

    Abstract: A ferromagnetic-polymer composite material comprises a polymer and a plurality of ferromagnetic film platelets disposed in the polymer. Each ferromagnetic film platelet comprises first and second insulator layers and a ferromagnetic layer disposed between the first and second insulator layers. The ferromagnetic layer can be magnetically anisotropic in which a hard axis of magnetization is aligned parallel to a plane that passes through and parallel to an interface between the first insulator layer and the ferromagnetic layer. The easy and/or hard axes of magnetization in the ferromagnetic film platelets can be aligned. An inductor can have a core formed of the ferromagnetic-polymer composite material.

    Abstract: A planar magnetic core includes multiple ferromagnetic layers including multiple hard ferromagnetic bias layers and multiple soft ferromagnetic layers. Each ferromagnetic layer comprises a soft ferromagnetic layer or a hard ferromagnetic bias layer. Each hard ferromagnetic bias layer is a neighboring ferromagnetic layer of at least one soft ferromagnetic layer. The planar magnetic core also includes a plurality of insulating layers, each insulating layer disposed between adjacent ferromagnetic layers. Each ferromagnetic layer has an easy axis of magnetization parallel to a principal plane of the planar magnetic core, where the easy axes of magnetization are aligned. Each hard ferromagnetic bias layer is magnetized to create an in-plane bias magnetic flux through the hard ferromagnetic bias layer in a first direction that is parallel to the easy axis of magnetization and forms a closed path through a neighboring soft ferromagnetic layer in a second direction parallel to the first direction.
