Reduced common mode voltage emission converter
This technology is a power converter — the kind of electronics that converts and regulates electrical power between a source and a load — designed to dramatically reduce a specific type of electrical noise called common mode electromagnetic interference (EMI). It uses a specialized eight-switch circuit architecture combined with a novel four-phase switching pattern called 'quadrangular control mode' that coordinates when each switch turns on and off within every power cycle. This approach simultaneously reduces inductor ripple, enables soft switching (which cuts heat and switching losses), and suppresses the EMI emissions that plague conventional converters. The net result is a more efficient, quieter power converter that is easier to certify for electromagnetic compatibility standards.
What you could build
A high-efficiency DC-DC converter module with built-in EMI suppression, targeting power supply designers in electric vehicles, industrial motor drives, data center power distribution, and aerospace power systems — sectors where EMI certification costs and power density constraints are major design pain points.
Who in Virginia should care
Defense and aerospace contractors in Northern Virginia and the Hampton Roads corridor — Northrop Grumman, Leidos, General Dynamics — regularly face stringent EMI compliance requirements for military power electronics and would be natural licensees or development partners.
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.
