Abstract
A current measurement device, comprising three or more different positions, wherein each position has at least two magnetoresistances. The two magnetoresistances are two magnetoresistances which respectively have a first sensitive direction and an opposite second sensitive direction. Within a set range, the resistance value of the magnetoresistance has a linear relationship with a magnetic field at the position where the magnetoresistance is located. The sensitive directions of all magnetoresistances at different positions are the same or opposite. A magnetic field to be measured has a component in the sensitive direction of the magnetoresistance. At least at one position the component in the sensitive direction of said magnetic field is different from components in the sensitive direction of said magnetic fields at other positions. All the magnetoresistances are electrically connected to form a resistance network in which an output signal includes the signals of said magnetic fields, and does not include or includes an interference magnetic field signal that is less than a first preset intensity. The current measurement device eliminates the interference of an interference magnetic field with current measurement.
