CURRENT SENSOR AND HALL SENSOR USED FOR THE SAME

摘要

PURPOSE: A current sensor and a hall sensor for the same are provided to modify the frequency characteristic of the current sensor by adding a small conductor or a coil. CONSTITUTION: A current sensor includes a yoke(110), a hall sensor(120), and a compensating conductor(170). In the yoke, one end and another end facing one end form a gap. The hall sensor measures a current based on the strength of magnetic field induced in the yoke, and is arranged in the gap. The compensating conductor is parallelly arranged to the sensing side of the hall sensor and offsets air flux induced in the hall sensor.
