Phase-shift control that keeps resonant converters efficient
This technology is a smarter control method for the type of power converters used in high-efficiency electronics, EV chargers, and data center power supplies. A standard resonant converter uses a transformer made of multiple smaller transformer units; this invention lets the controller deliberately time-shift the switching of some of those units while keeping others in sync with the primary side. By selectively mixing in-phase and phase-shifted switching across these sub-transformers, the system can fine-tune power delivery and efficiency across a much wider range of operating conditions than conventional designs allow. The result is a converter that maintains high efficiency even when load or input voltage varies significantly.
What you could build
A high-efficiency DC-DC converter module for EV onboard chargers, data center power distribution units, or industrial power supplies; target buyers would be power electronics OEMs, hyperscaler infrastructure teams, and EV tier-1 suppliers seeking efficiency gains without redesigning transformer hardware.
Who in Virginia should care
Virginia-based defense contractors and data center operators (Northern Virginia is a global data center hub) would have direct interest in high-efficiency power conversion for both facility infrastructure and embedded power systems.
Readiness: Concept
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.
