Integrated-magnetics DC-DC converter for EV and data centers
This technology is a compact, high-efficiency power converter that combines multiple magnetic components — normally separate transformers and inductors — into a single integrated magnetic core. It runs three converter circuits in parallel (interleaved), which smooths out power ripple and reduces stress on components. By cleverly varying how wires are wound around different parts of the core, engineers can tune the resonant behavior of each circuit without adding extra parts. The result is a smaller, lighter, more efficient power conversion stage suitable for high-power applications like EV chargers or data center power supplies.
What you could build
A compact, high-density bidirectional DC-DC converter module for electric vehicle onboard chargers or vehicle-to-grid systems; buyers would be EV OEMs, Tier 1 automotive suppliers, and data center power supply manufacturers seeking higher power density in a smaller footprint.
Who in Virginia should care
Defense contractors and naval shipbuilders in the Hampton Roads area, or data center operators in Northern Virginia's data center corridor, would have direct interest in compact high-efficiency power conversion.
Readiness: Prototype likely
Concept — described but not yet demonstrated. Lab validated — supported by experimental results in the patent. Prototype likely — the text describes a built, working embodiment.
Readiness is inferred from the patent text, not from a lab visit.
