Compact high-performance inductor with redistributed flux
This technology is a design method for building smaller, more efficient inductors — the coil-based components used to manage electrical current in virtually every power circuit. The key innovation is a mathematical approach to redistributing the magnetic field evenly across multiple nested coil windows, which prevents the core from saturating (overloading) and generating excess heat. The result is an inductor that delivers the same electrical performance as a conventional part but in a smaller footprint and with lower energy loss. The design process is iterative and deterministic, meaning engineers can specify their target inductance and resistance and work backward to a manufacturable geometry.
What you could build
A licensed inductor design kit or parameterized reference design sold to power electronics manufacturers or embedded in EDA (electronic design automation) software; buyers would be power supply OEMs, DC-DC converter makers, and board-level integrators in consumer electronics, automotive power, and industrial equipment.
Who in Virginia should care
Defense and aerospace contractors in Northern Virginia and the Hampton Roads corridor — particularly those designing compact power systems for shipboard electronics, UAVs, or military ground vehicles — would have direct interest in compact, high-efficiency magnetics.
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.
