Abstract
A current sensor includes: a magnetic core that surrounds a detected object; a first sensor with a first sub-magnetic core incorporated in the magnetic core and a first winding wound around the first sub-magnetic core; a second sensor with a second sub-magnetic core incorporated in the magnetic core and a second winding wound around the second sub-magnetic core in the opposite direction to the first winding; a signal generator outputting signals to magnetize the first and second windings with inverted phases; a detector outputting a detection signal whose amplitude is proportionate to a current in the detected object based on the difference between first and second voltage signals generated in the first and second windings; and a waveform adjuster that is connected to at least one of the first and the second windings and adjusts the waveform of a voltage signal generated by the connected winding.
