Coupled-inductor power module with low winding resistance
This technology is a more efficient power converter for electronics that need to handle multiple voltage levels simultaneously. Traditional designs waste energy because the wire coils (inductors) in the circuit loop around a magnetic core, adding electrical resistance. Here, the inductors are straight conductors — essentially straight lines on a circuit board — while a specially shaped magnetic core weaves around them instead. This reversal reduces resistance, cuts heat generation, and makes the converter respond faster to sudden changes in power demand.
What you could build
A drop-in power conversion module for high-performance computing hardware (servers, GPUs, CPUs) and telecommunications equipment where power efficiency and fast load response are critical; target buyers are server board ODMs, semiconductor packaging firms, and power management IC companies integrating passive components.
Who in Virginia should care
Defense electronics contractors and data center operators in Northern Virginia — both sectors demand compact, high-efficiency power management on dense circuit boards.
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.
