PCB-embedded coupled inductors for EV onboard PFC chargers
This technology is a smarter power conversion circuit for devices that draw electricity from the grid, designed to make that conversion more efficient and cleaner. It uses specially designed inductors — the components that manage electrical current — built directly into a multi-layer circuit board rather than as bulky separate parts. By coupling these inductors together in a specific way, the circuit naturally switches power on and off at lower stress points, reducing energy waste and electromagnetic interference. The design is particularly well-suited for electric vehicle chargers that need to push power both to and from the battery, enabling vehicle-to-grid capabilities.
What you could build
A compact, high-efficiency onboard battery charger module for electric vehicles — integrating PCB-embedded coupled inductors — sold to EV OEMs or Tier 1 automotive suppliers who need smaller, lighter chargers with bidirectional (V2G) capability.
Who in Virginia should care
Virginia-based defense and automotive electronics suppliers, as well as EV fleet operators tied to the Port of Virginia logistics corridor, would have direct interest in compact bidirectional charging hardware.
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.
