Simplified optimal trajectory control for resonant DC-DC
This technology is a smarter control system for resonant power converters — the circuits that efficiently regulate electricity in devices like laptops, data center power supplies, and EV chargers. Instead of relying on complex internal measurements, it uses just two simple readings: output voltage and load current. A microcontroller uses those two signals and a pre-calculated lookup table to rapidly adjust the converter's switching behavior, keeping power delivery stable and efficient even when the electrical load changes suddenly. The design also supports a low-power 'burst mode' and a smooth startup sequence, all without requiring high-cost components.
What you could build
A power management IC or reference design for high-efficiency DC-DC converters used in data center server power supplies, EV onboard chargers, or consumer electronics adapters; target buyers are power semiconductor companies and OEM power supply manufacturers.
Who in Virginia should care
Northern Virginia data center operators and their power supply vendors, plus defense electronics primes in the DC-metro corridor needing efficient converter designs.
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.
