ABSTRACT:
Apparatus and method for effectively decreasing current spike, ringing, and electromagnetic noise in a circuit containing a semiconductor device when a voltage applied to the semiconductor is inverted. The core of the reactor is made of an amorphous magnetic alloy having a magnetic flux density of not less than 6 kilogauss at an external magnetic field of 1 oersted, a coercive force of not more than 0.5 oersted, and a squareness ratio of not less than 0.8 when a frequency is set to be 100 kilohertz. The reactor includes the core having a through hole and conductor wound around the core through the through hole. The core is insulated from the conductor.
