Distributed-gap inductor for low-loss, high-frequency power
This patent describes a new type of inductor — a core electrical component used to store and manage energy in circuits — that uses a layered, distributed-gap core design wrapped with a helical winding. Instead of concentrating the magnetic gap in one place (which causes energy losses and heat), the design spreads the gaps across multiple layers throughout the core. This reduces electromagnetic interference, lowers energy losses, and allows the component to handle higher currents more efficiently. The result is a physically compact inductor that performs better than conventional designs in demanding power electronics applications.
What you could build
A high-efficiency inductor component for power converters and inverters used in EV charging systems, data center power supplies, or industrial motor drives — sold to power electronics OEMs or procured by defense/aerospace power system integrators.
Who in Virginia should care
Defense and aerospace prime contractors in Northern Virginia and Hampton Roads with power electronics needs, as well as data center operators concentrated in Northern Virginia seeking more efficient power conversion components.
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.
