Frequency-agnostic electronic transformer for dense power
This technology is a compact, highly efficient power converter that uses a novel 'electronic embedded transformer' built directly into a circuit board. The transformer uses a capacitor and a small bridge of switches to electronically cancel out the energy losses that normally occur at the transformer's magnetic windings, and it does this across any operating frequency rather than only at a fixed tuned point. The result is stable voltage conversion and balanced current sharing between parallel converter modules without the bulky, frequency-sensitive components traditional designs require. Because the key components are integrated onto a PCB, the design is inherently manufacturable at scale and suited for compact, high-density power systems.
What you could build
A high-density DC-DC power converter module for data center power distribution, electric vehicle onboard chargers, or telecom infrastructure — sold to power electronics OEMs or hyperscale data center operators who need compact, frequency-agnostic, high-efficiency conversion at scale.
Who in Virginia should care
Northern Virginia hyperscale data center operators and their power supply chain vendors would be natural targets, as would defense electronics primes in the region needing compact high-density power conversion.
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.
