Abstract
A system and method for current sensing includes a conductor configured to receive current flow therethrough and generate magnetic flux thereabout. The current sensor system also includes an anti-differential current sensor configured to monitor magnetic flux about the conductor. The anti-differential current sensor includes a pair of current sensors in opposing positions and disposed in the flux concentrating recesses of the conductor, and a processing component configured to receive feedback from each of the current sensors. The processing component is further configured to output a value indicative of the amount of current flow in the conductor.
