Symmetrically efficient bidirectional three-phase DC/DC
This technology is a power converter that moves electrical energy between two DC voltage systems in either direction with equal efficiency. It uses a three-phase architecture with matched resonant circuits and transformers on both sides, making the forward and reverse power flow perform identically. Think of it as a highly symmetrical electrical bridge that can charge a battery from a power grid and then discharge that same battery back to the grid without losing conversion efficiency in either direction. The symmetrical design simplifies control and avoids the tuning mismatches that plague conventional bidirectional converters.
What you could build
A power electronics module for grid-tied battery energy storage systems, electric vehicle charging infrastructure with vehicle-to-grid capability, or data center UPS systems — sold to power electronics OEMs, EV charging equipment manufacturers, or industrial energy storage integrators.
Who in Virginia should care
Defense contractors and naval facilities in Hampton Roads and Northern Virginia with bidirectional power needs, plus data center operators concentrated in Northern Virginia, would be natural contacts.
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.
