Series-series resonant circuit for efficient wireless charging
This technology is a smarter circuit design for wireless charging systems — the kind used in electric vehicles, medical implants, and consumer electronics. It uses a specific arrangement of capacitors and inductors (called a series/series resonant topology) to convert power more efficiently by minimizing wasted reactive energy. The design automatically maintains a stable output voltage even as the load changes, which is a persistent challenge in wireless power transfer. The result is a more efficient, compact charging system that doesn't require as much active control circuitry.
What you could build
A licensed circuit topology for wireless EV charging pads or medical device charging systems that improves efficiency and reduces heat and component cost; target buyers would be EV charging hardware manufacturers and medical device OEMs.
Who in Virginia should care
Virginia-based defense and aerospace contractors (e.g., those in the Northern Virginia corridor) developing wireless power for UAVs or autonomous ground vehicles, as well as EV infrastructure companies serving the Mid-Atlantic market.
Readiness: Lab validated
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.
