Transformer with built-in resonant inductance for DC-DC
This technology is a compact transformer design for power converters that cleverly builds the resonant inductor directly into the transformer itself, eliminating the need for a separate component. It achieves this by varying the number of wire turns on different legs of the magnetic core and alternating the winding direction between adjacent legs, which creates a controlled, built-in magnetic leakage. The result is a single integrated component that does the work of two, reducing size, weight, and assembly complexity in power conversion systems. This is particularly relevant for high-frequency DC-to-DC converters used in applications where board space and efficiency are at a premium.
What you could build
A drop-in integrated magnetic component for high-frequency DC-DC converters used in data center power supplies, EV onboard chargers, and telecom power systems; purchased by power electronics OEMs and their tier-one suppliers.
Who in Virginia should care
Defense electronics and data center infrastructure companies in Northern Virginia, including power supply vendors serving hyperscalers and defense primes, would have direct interest.
Readiness: Concept
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.
