摘要： A current sensor system for measuring an AC electrical current, comprising: a busbar having a thickness and a width; a sensor device comprising two sensor elements spaced apart along a first direction for measuring two magnetic field components oriented in a second direction; the sensor device configured for determining a magnetic field difference, and for determining the AC current based on said difference. The sensor device is positioned relative to the busbar such that a reference point in the middle between the two sensor elements is located at a first distance from a side of the busbar from 70% to 110% or from 70% to 95% of the width of the busbar and is located at a second distance from 0.5 to 4.0 mm from the busbar.

摘要： The present invention relates to a current-sensor structure comprising a conductor for conducting electrical current in a current direction. The conductor has one or more conductor surfaces. At least one current sensor is disposed on, over, adjacent to or in contact with the conductor and is offset from a centre of the conductor in an offset direction orthogonal to the current direction and optionally parallel to a conductor surface. The current-sensor structure can comprise a substrate on which the conductor is disposed. The current sensor can be located on a side of the conductor opposite or orthogonal to a surface of the substrate. The current sensor can be aligned with, near to or adjacent to an edge of the conductor. The current-sensor structure can comprise a shield, such as a U-shaped laminated shield that at least partially surrounds the conductor and the current sensor.

摘要： A current sensor system for accurately measuring an AC electrical current having frequencies up to 2 kHz, the system comprising: an electrical conductor (e.g. busbar) for conducting said AC current thereby creating a first magnetic field; a magnetic sensor device for measuring a magnetic field component or gradient; an object (e.g. a metal plate) having an electrically conductive surface arranged in the vicinity of said conductor for allowing eddy currents to flow in said surface, thereby creating a second magnetic field which is superimposed with the first magnetic field; wherein the magnetic sensor device is configured for determining the current as a signal or value proportional to the measured component or gradient. The metal plate may have an opening. The current sensor system may further comprise a shielding.

摘要： A current sensor system has a conductor and a packaged integrated circuit for sensing a current in the conductor. The conductor is external to the packaged integrated circuit. The packaged integrated circuit includes a substrate having an active surface and a back surface; one or more magnetic sensing elements; a processing circuit arranged to process signals received from the one or more magnetic sensing elements to derive an output signal indicative of a sensed current in the conductor; a housing; a plurality of leads; electrical connections between the leads and the active surface. The back surface of the substrate is disposed on a support formed by at least two inner lead portions of the plurality of leads and the active side of the substrate is oriented towards the outer ends of the outer lead portions of the leads in a direction perpendicular to a plane defined by the support.
