Low-resistance coupled inductors for multiphase voltage
This technology describes a compact, flat inductor assembly designed for power converters that manage voltage across multiple channels simultaneously. By winding the inductors through a ladder-shaped magnetic core in opposing directions, the design achieves 'inverse coupling,' which reduces current ripple and improves efficiency. The flat, board-mountable geometry also keeps electrical resistance low, which means less energy wasted as heat. The net result is a smaller, more efficient power management component suitable for high-density electronics.
What you could build
A drop-in coupled inductor component for multiphase voltage regulators used in server motherboards, GPU power stages, and high-performance computing hardware; the primary buyers would be power component manufacturers like Vishay, Bourns, or Coilcraft, and OEM electronics manufacturers designing power delivery networks for CPUs and AI accelerators.
Who in Virginia should care
Northern Virginia's dense data center corridor creates ongoing demand for efficient server power management components; companies like AWS, Microsoft Azure, or their hardware supply chain partners operating in the region would have direct interest.
