Title:
INDUCTOR AND DC/DC CONVERTER INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2023139568
Kind Code:
A
Abstract:
To provide an inductor further increased in inductance.SOLUTION: An inductor 10 includes: a magnetic core 100 formed by laminating a plurality of soft magnetic thin bands 131 in a Z direction; and a first coil conductor 110 inserted into first and second penetration holes 101, 102 that penetrate through the magnetic core 100 in the Z direction and that are arranged in an X direction. Each of the soft magnetic thin bands 131 is divided into a plurality of small pieces P by gaps G. When a2 represents an average interval of the gaps G in the X direction and a1 represents an average interval of the gaps G in a Y direction, a1 is larger than a2. Therefore, the cancellation of magnetic fluxes is decreased, so that the inductance of the inductor can be increased.SELECTED DRAWING: Figure 5
