Fast-transient quasi-parallel voltage regulator module
This technology is a power supply architecture that splits the work of delivering power between two parallel branches—one that regulates voltage precisely and one that delivers bulk current without regulation—each fed by separate input power sources connected in series. The clever series connection of the input sources creates a natural feedback loop that helps the regulated branch maintain stable output voltage without extra circuitry. The design also borrows a technique of staggering the switching of inductor-free resonant converters to cancel out the voltage ripple that would normally make them impractical. The net result is a power supply that responds faster to sudden load changes and regulates more tightly than conventional single-branch designs.
What you could build
A high-performance DC power supply module for servers, telecommunications equipment, or industrial electronics where fast transient response and stable voltage are critical; likely sold to power electronics OEMs or integrated into data center power delivery hardware.
Who in Virginia should care
Data center operators and power electronics manufacturers with a presence in Northern Virginia's dense data center corridor would have direct interest in improved power supply architectures.
Readiness: Lab validated
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.
