Abstract

See full text

A current sensor includes: four first uniaxial TMR chips and at least two second uniaxial TMR chips, each first uniaxial TMR chip and each second uniaxial TMR chip being located on the same virtual ring, wherein magnetic sensitive directions of the four first uniaxial TMR chips are perpendicular to a radius of the virtual ring, magnetic sensitive directions of two adjacent first uniaxial TMR chips are perpendicular to each other, magnetic sensitive directions of the two second uniaxial TMR chips are parallel to the radius of the virtual ring and opposite to each other, and the two second uniaxial TMR chips respectively have the same positions as two first uniaxial TMR chips; each first uniaxial TMR chip and each second uniaxial TMR chip are configured to collect a magnetic induction intensity, the magnetic induction intensity is configured to calculate a target current value of a to-be-measured wire.
