Integrated magnetics bidirectional converter for EV and data
This technology is a compact, highly efficient power converter that combines multiple conversion stages and their magnetic components into a single, unified structure. Traditional power converters use separate transformers and inductors, which take up space and add cost; this design merges them into one magnetic core using a clever winding arrangement across multiple core legs. The result is a three-phase resonant converter that can transfer power bidirectionally—useful for charging and discharging—with reduced size, weight, and component count. Multi-layer circuit board windings further simplify manufacturing and integration.
What you could build
A compact, high-efficiency bidirectional DC-DC converter module for electric vehicle onboard chargers or data center power supplies, sold to Tier 1 automotive suppliers, EV OEMs, or hyperscale data center infrastructure vendors.
Who in Virginia should care
Defense contractors and data center operators concentrated in Northern Virginia, plus automotive electrification suppliers serving the mid-Atlantic region, would have direct use for compact, high-efficiency DC-DC converter modules.
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.
