Abstract

PURPOSE:To vary inductance through DC overlap, and to miniaturize the choke coil by winding winding on a magnetic core manufactured by unifying a core of a high magnetic flux density material and a core having high permeability. CONSTITUTION:The magnetic core 21 is constituted by unifying the core 211 of the high magnetic flux density material and the core 212 of a high permeability material. The winding 22 is wound on the magnetic core 21, and used as the choke coil. The E type core 5 is made of the high permeability material, the I type core 6 in the high permeability material is stacked on the core 5 through a gap 8 and unified, the winding 7 is wound on the magnetic core unified and employed as the choke coil, and the magnetic reluctance of the cores 5, 6 is increased by the gap 8. The choke coil constituted in this manner is connected in series with a load circuit of a switching regulator, etc. and used, DC currents are overlapped to the choke coil, high inductance is obtained by means of the choke coil when load currents are small, low inductance is acquired when the load currents are large, and voltage can be absorbed positively.
