Interleaved power converter with shared integrated magnetics
This technology describes a compact, high-efficiency power conversion system that combines multiple converter circuits and their magnetic components into a single integrated unit. Traditional power converters use separate, bulky components for each phase, but this design merges the inductors and transformers across three phases into one shared magnetic core. The result is a smaller, lighter power converter that loses less energy as heat and can be manufactured using multi-layer printed circuit boards for the windings. It is particularly suited for bidirectional power conversion, meaning it can move power in both directions — useful for charging and discharging applications.
What you could build
A compact, high-efficiency bidirectional onboard charger or DC-DC converter module for electric vehicles or industrial power supplies; primary buyers would be EV powertrain suppliers, industrial UPS manufacturers, and data center power system integrators.
Who in Virginia should care
Virginia-based defense contractors, naval facilities, and data center operators (Northern Virginia is a global data center hub) would have strong interest in compact, efficient high-power conversion 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.
