PCB-integrated current sensing layer for power converters
This technology embeds a current-sensing coil directly into a printed circuit board, sandwiched between the positive and negative DC power traces that carry current through a power converter. The coil — a Rogowski design, which measures current without direct electrical contact — is sized to extend slightly wider than the traces it monitors, improving measurement accuracy. Because the sensor is part of the board itself rather than a separate clip-on component, it eliminates the need for bulky external current sensors and reduces assembly steps. The result is a more compact, lower-cost power electronics module with built-in current feedback for control and protection.
What you could build
A PCB-integrated current sensing layer sold as a design element or reference design to power electronics manufacturers building DC-DC converters, inverters, or EV charging modules — targeted at companies that need isolated current measurement without added components.
Who in Virginia should care
Power electronics suppliers and defense contractors in Northern Virginia and the Hampton Roads corridor — particularly those developing EV charging infrastructure or naval power conversion systems — would find direct application.
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.
