PROBLEM TO BE SOLVED: To provide a magnetic coupling type reactor reduced in leak magnetic flux to the outside.SOLUTION: A magnetic coupling type reactor comprises: an annular core including two U-shaped cores 1a, 1b and two I-shaped cores 2a, 2b. The annular core has: pairs of outer legs opposed to each other; a pair of yoke parts connecting to ends of each pair of outer legs; and intermediate legs provided in parallel with the pair of yoke parts. At the center between the intermediate legs, a gap is formed in parallel with the outer legs. The magnetic coupling type reactor further comprises: at least two coils 3a, 3b attached to the annular core so that they produce magnetic fluxes different in direction. It is preferable that a gap length ratio B/A, which is a ratio of the length B of the gap to the distance A between the opposed outer legs, is in a range of 0.1-0.9, and a cross section ratio D/C, which is a ratio of the cross section D of the intermediate legs to the cross section C of the outer legs, is in a range of 0.1-1.0.SELECTED DRAWING: Figure 2 |
