Wide-range quasi-parallel DC-DC voltage regulator
This technology is a smarter way to build power converters — the electronic components that transform one voltage level into another. It uses two converters working together: their inputs are wired in series (stacked) while their outputs are combined in parallel, and an intelligent controller decides how to run each converter based on the actual input and output voltages at any moment. When the input voltage is high and the output is low, the controller runs the first converter above its natural resonant frequency; when input is low and output is high, it runs below resonance. This adaptive approach allows the system to maintain high efficiency across a much wider range of operating conditions than conventional single-converter designs.
What you could build
An efficient DC-DC power conversion module for applications with wide voltage swings — such as electric vehicle on-board chargers, data center voltage regulators, or solar/battery storage systems — sold to power electronics OEMs or integrated into power supply reference designs for automotive and server manufacturers.
Who in Virginia should care
Northern Virginia data center operators and their power supply vendors, or defense electronics contractors managing wide-range DC power systems.
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.
