What they work on

  1. Develop rapid yet accurate models of energy loss in inductors and transformers at MHz frequencies, so magnetic component designs can be optimized quickly.
  2. Create new magnetic component structures that suppress high-frequency eddy currents, the stray currents that waste energy, while staying practical to manufacture.
  3. Investigate new magnetic materials, and repurpose existing ones, for low-loss power conversion at MHz frequencies.
  4. Build engineered platforms to characterize magnetic cores and full components accurately at MHz and tens-of-MHz frequencies.

More about the research

If converters switched ten times faster, they would need to store ten times less energy, so they could be smaller and more efficient. The main obstacle is the magnetic components, the inductors and transformers. At megahertz (MHz) frequencies, millions of cycles per second, these components lose much of their energy.

Why it matters

Smaller, more efficient power converters could support wider use of renewable energy and lighter, more affordable electric vehicles. They could also help electrify ships and aircraft and make semiconductors more affordable. Engineers designing power electronics would gain better models, designs, and measurement tools for high-frequency magnetics.

Known grants

From NIH and NSF research grants. Labs often have other funding we can't see.
