Abstract
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.
