Abstract

The hall sensor is current detector using hall effect in semiconductor and the conventional type detect current with concentrating flux by current of conductor. So, detection of small current is very difficult because of residual magnetism. This paper give the experiments based results about method that detect the small DC current using minimizing the residual of hall element by magnetic modulation and concentrating flux. The suggested sensor can dector small current better than the conventional that.
