Magnetic sensor

摘要

A magnetic sensor includes a magnetic detection element, and a correcting section to correct an output voltage of the magnetic detection element and output the corrected output voltage. The correcting section is configured to compute a magnetic flux density from the output voltage of the magnetic detection element, compute and output the corrected output voltage having a linear relationship to the computed magnetic flux density.

1. A magnetic sensor, comprising:
a single magnetic detection element that detects an electric current conducted through a single current path by outputting a voltage that is dependent upon a magnetic flux density generated by the electric current, wherein the relationship between the output voltage and the magnetic flux density is nonlinear; and a correcting section that corrects the output voltage of the magnetic detection element such that the relationship between the output voltage and the magnetic flux density is linear and outputs the corrected output voltage, wherein the correcting section is configured to compute a magnetic flux density from the corrected output voltage of the magnetic detection element, and to compute and output a value of the electric current that generated the magnetic flux density.
