Abstract
This paper describes a compact three-phase electric current sensor using a magneto-impedance (MI) sensor for wide-range current sensing. The MI sensor is composed of a thin-film MI element and a bias coil. Double shields are used for high shielding performance maintaining compact size. Two kinds of alternating bias are used in the system to achieve a wide measurement range of 1:600. Furthermore, using optimized carrier electric current is shown to decrease the temperature dependence of the MI sensor
