PROBLEM TO BE SOLVED: To provide a hollow cylindrical reactor device which is suitable for making a power unit small-sized and lightweight while suppressing the generation of noise further than the prior arts.SOLUTION: A hollow cylindrical reactor device 1 comprises an inductance element 2 in an approach path and a return conductor 6 in a return path. The inductance element 2 includes around a center axis AX a coil 3 around which an insulation coated conductor is wound. The inductance element 2 is cylindrical or annular with the hollow center axis AX and the return conductor 6 is cylindrical while sharing the center axis AX and disposed at a coaxial outer peripheral side of the inductance element 2. Further, other hollow cylindrical circuit elements are combined in the hollow cylindrical reactor device 1, such that a hollow cylindrical converter device and a hollow cylindrical power unit can be formed. |
