Title:
INDUCTOR AND DC/DC CONVERTER INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2023139567
Kind Code:
A
Abstract:
To provide an inductor which is further reduced in coupling between coil conductors.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 first and second coil conductors 110, 120 respectively 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 a1 represents an average interval of the gaps G in the X direction and a2 represents an average interval of the gaps G in a Y direction, a1 is smaller than a2. Therefore, the coupling coefficient between the first coil conductor 110 and the second coil conductor 120 is lowered.SELECTED DRAWING: Figure 3
