Configurable planar transformer with adjustable turn ratio
This technology is a compact, flat (planar) transformer designed for power converters—the components that convert electricity from one voltage level to another in devices like EV chargers, data center power supplies, and industrial equipment. Unlike conventional transformers, this design uses a specially structured magnetic core with multiple legs and auxiliary sections, allowing engineers to tune both the turns ratio and the leakage inductance (a parameter that affects efficiency and resonant behavior) without redesigning the whole unit. The interleaved winding arrangement reduces electromagnetic interference and heat. The result is a single hardware platform that can serve multiple output voltage requirements with less custom engineering work per application.
What you could build
A configurable planar transformer module sold to power electronics manufacturers for use in EV fast chargers, data center power delivery units, and industrial DC-DC converters—buyers would be power supply OEMs and tier-1 EV charging equipment makers seeking to reduce design iterations and component SKU count.
Who in Virginia should care
Defense electronics and data center power supply companies with engineering presence in Northern Virginia, plus EV infrastructure firms expanding along the I-95 corridor, would have direct application interest.
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.
