Three-phase LLC converter with integrated magnetics
This technology is a compact, high-efficiency power converter that combines multiple magnetic components—normally separate transformers and inductors—into a single integrated core structure. It uses a three-phase interleaved design, meaning it staggers power conversion across three parallel channels to reduce electrical ripple and improve overall performance. By weaving the windings around a six-leg transformer core in a specific geometric arrangement, the design eliminates redundant hardware and reduces size and weight. The result is a more efficient, smaller power conversion unit compared to conventional single-phase or non-integrated designs.
What you could build
A compact DC-DC power converter module for electric vehicle charging stations, data center power supplies, or renewable energy inverters, sold to power electronics OEMs or tier-1 EV charging infrastructure suppliers seeking higher power density in constrained form factors.
Who in Virginia should care
Virginia-based defense contractors, data center operators in Northern Virginia, and EV infrastructure developers along the I-95 corridor would be natural targets for this technology.
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.
