Integrated transformer DC-DC module eliminating discrete
This technology redesigns the transformer at the heart of a high-current power converter so that it eliminates the need for separate, discrete inductors. By winding a special 'coupling winding' around multiple magnetic cores, the transformer magnetically links those cores together and uses its own internal inductance to do the job that stand-alone inductors would normally do. The result is a more compact, integrated power converter output stage with fewer components. This matters most in applications demanding high current in a tight space, such as server power supplies, EV onboard chargers, or industrial DC-DC converters.
What you could build
A compact, high-efficiency DC-DC power converter module with an integrated transformer eliminating discrete inductors, sold to power supply manufacturers serving data center, EV, or telecom infrastructure markets.
Who in Virginia should care
Defense and data center power supply manufacturers with Virginia facilities — including primes like Leidos, BAE Systems, and hyperscaler data center operators in Northern Virginia — would have direct interest in compact, high-current converter technology.
Readiness: Lab validated
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.
