Document Type and Number:
Japanese Patent JP2018156974
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a three-phase tripod magnetic core and three-phase tripod inductor capable of equalizing excitation inductance of each phase with low loss.SOLUTION: A three-phase tripod magnetic core includes three legs (2, 2A, ..., and 2Q) composed of leg members each including a winding portion (3a) around which a conductive wire is wound, and that forms a space (16) in which coil windings (8) to be formed on the winding portions are arranged to be separated from each other without mutual interference and joints (4-4, 4A-4A, ..., and 4Q-4Q) directly joined to each other or indirectly joined to each other via another member at a point where one of the leg members constituting the leg meets the other leg member such that the three legs electromagnetically communicate with each other.SELECTED DRAWING: Figure 2
