PROBLEM TO BE SOLVED: To prevent the coupling coefficients from becoming extremely high while reducing the Joule loss, when reverse phase currents flow through two coils, without increasing the size excessively in a magnetic coupling reactor.SOLUTION: A magnetic coupling reactor 10 includes a coupling core member 20, a first coil 60 and a second coil 61. The coupling core member 20 includes a first core 21 and a second core 31 formed of a magnetic material and arranged oppositely, a coil passage 45, and sheet-like magnetic materials 50, 51 by which the inter-core coupling portion 54 is sandwiched on the outside of the first and second cores. The coils 60, 61 are wound around intermediate legs 23, 33 while passing through the coil passage 45, and wound to be superposed alternately in the coil passage 45, when viewing in the axial direction. Each sheet-like magnetic material has an inter-coil arrangement portion 56 extending from the inter-core coupling portion 54 into the coil passage 45, and arranged between the coils 60, 61 in the axial direction.SELECTED DRAWING: Figure 2 |
