Title:
CURRENT SENSOR
Document Type and Number:
Japanese Patent JP2020095029
Kind Code:
A
Abstract:
To provide a current sensor device for measuring an electric current.SOLUTION: A current sensor device (400) for measuring an electric current includes: a substrate (410) equipped to an electric conductor (413) with a symmetry plane (Ω), the substrate (410) having a first magnetic sensor and a second magnetic sensor (411, 412), the first magnetic sensor being located in a first place outside the symmetry plane and providing a first value (v1) showing a first magnetic component induced by a current and the second magnetic sensor being located in a second place in the symmetry plane (Ω) and providing a second value (v2) showing a disturbance magnetic field; and processing circuits (610; 710) connected to the first and second magnetic sensors and adjusted to determine the current based on the difference between the first and second values (v1 and v2).SELECTED DRAWING: Figure 3
