Integrated multiphase buck converter with controllable
This technology is a compact, integrated inductor design for multiphase buck converters — the circuits that step down voltage to power processors, servers, and other electronics. Instead of using separate coupling components, the design weaves magnetic coupling directly into a shared magnetic core structure, allowing multiple power stages to work together more efficiently. A control winding lets engineers adjust the coupling between stages dynamically, tuning performance for different load conditions. The result is a smaller, potentially more efficient power delivery system compared to conventional discrete designs.
What you could build
An integrated power module for server CPUs, GPUs, or AI accelerator boards that delivers tighter voltage regulation in a smaller footprint; primary buyers would be data center hardware OEMs and semiconductor companies designing voltage regulator modules (VRMs).
Who in Virginia should care
Northern Virginia data center operators and hardware suppliers to hyperscalers (AWS, Microsoft, Google) with facilities in the region would have direct procurement interest in more efficient power delivery components.
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.
