Patent ID: 8847588

Claim:
A current sensor comprising: a measurement current path configured to flow a measurement current therethough; a neighboring current path provided in a vicinity of the measurement current path, and configured to flow a neighboring current therethrough; a first magnetoelectric transducer having a first main sensitivity axis and provided on a first side of the measurement current path, the first main sensitivity axis being oriented in parallel to and in a same direction as a direction of a magnetic field applied from the measurement current; a second magnetoelectric transducer having a second main sensitivity axis and provided on a second side of the measurement current path, the second main sensitivity axis being oriented in parallel and opposite to a direction of the magnetic field applied from the measurement current; a third magnetoelectric transducer having a third main sensitivity axis and provided on the first side of the measurement current path, the third main sensitivity axis being oriented orthogonal to a direction of the magnetic field applied from the measurement current, and non-orthogonal to a direction of a magnetic field applied from the neighboring current; and a fourth magnetoelectric transducer having a fourth main sensitivity axis and provided on the second side of the measurement current path, the fourth main sensitivity axis being oriented orthogonal to a direction of the magnetic field applied from the measurement current, and non-orthogonal to a direction of the magnetic field applied from the neighboring current.
