Integrated matrix transformer with tunable leakage inductance
This technology is a new type of transformer design that combines multiple power conversion functions into a single compact magnetic component. By adding a specially placed 'leakage core leg' inside the transformer's core structure, engineers can precisely tune how much energy is temporarily stored and released during power conversion — a parameter that normally requires a separate physical component. The planar (flat) winding layout makes the design manufacturable using standard printed circuit board techniques, keeping it thin and scalable. The result is a more integrated, efficient power converter that takes up less space and has fewer parts.
What you could build
A drop-in magnetic component for high-density DC-DC power converters used in data center power supplies, EV onboard chargers, and telecom infrastructure — sold to power electronics OEMs and their Tier 1 component suppliers as a pre-engineered module or licensed design.
Who in Virginia should care
Data center operators and power electronics firms with a Northern Virginia or Richmond footprint — including hyperscaler campuses — would be natural partners for efficiency-driven power supply components.
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.
