Abstract

Systems and methods are described herein for reducing the effects of magnetic field cross- coupling in a multi-conductor current sensor system. A current sensor system includes one or more current sensors, each positioned proximate to at least one conductor and spaced from at least one other conductor. Each conductor carries a current intended to be measured by a respective current sensor. The current sensors include one or more magnetic field sensing elements to generate a magnetic field signal indicative of a detected magnetic field. A characterization measurement is performed to determine the coupling between each current sensor and the respective current conductor and to determine the coupling between the current sensor and the other ones of the current conductors, by providing a reference current to each of the conductors and measuring the outputs at each of the current sensors. The characterization measurement can be used to generate a coupling matrix.
