Passive high-frequency power components
Passive high-frequency power components
Passive high-frequency power components are often the limiting factors in reducing the power loss, size, cost, and weight of high-frequency electronic power converters. Through detailed analysis, modeling, and optimization of high-frequency effects in inductors, transformers, and capacitors, we are improving performance of these components and making it easier to design the efficient, low-cost power electronics needed for a wide range of applications including energy efficiency and renewable energy.

Microfabricated magnetic components using nanomaterials
Microfabricated magnetic components using nanomaterials
Microfabricated magnetic components using nanomaterials make it possible to miniaturize power-handling magnetic components through taking advantage of the materials' high-flux-density and high-frequency capabilities. We are developing practical methods of depositing these materials and fabricating inductors and transformers on silicon chips or in other technologies.
