Integrated transformer-inductor for high-density DC-DC
This technology is a compact, high-efficiency power conversion component that combines two transformers and two inductors into a single integrated magnetic structure. By splitting the primary electrical current equally across two parallel paths, it reduces energy losses from heat and electromagnetic interference that plague conventional designs. The flat, planar winding layout makes it suitable for dense circuit board assemblies where space and thermal management are critical. It is particularly relevant for high-frequency DC-to-DC power converters used in data centers, telecom equipment, and fast-charging systems.
What you could build
A drop-in integrated magnetic component for high-density power supplies targeting hyperscale data center power delivery units and telecom base station power modules; power supply manufacturers and ODMs building 48V bus converters would be the primary buyers.
Who in Virginia should care
Northern Virginia hosts the world's largest concentration of data center capacity, making power supply manufacturers and data center infrastructure suppliers there natural commercial partners or licensees.
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.
