Abstract:
1. A reactor comprising: a main coil formed by spirally winding a wire; a sub-coil formed by spirally winding a wire that is different from the wire constituting the main coil; and a magnetic core to which both the main coil and the sub-coil are arranged, the magnetic core forming a closed magnetic path, wherein the sub-coil: wherein the main coil and the magnetic core are configured to function as a reactor for smoothing, wherein the sub-coil and the magnetic core are configured to function as a reactor for resonance, wherein the main coil is an edgewise coil that is formed by winding a coated rectangular wire in an edgewise manner, the coated rectangular wire including a conductor made of a rectangular wire and an insulating coating layer formed on an outer periphery of the conductor, wherein the wire constituting the sub-coil is: wherein a center position of the main coil in an axial direction thereof and a center position of the sub-coil in an axial direction thereof are shifted from each other in the axial direction, wherein a length of one of the main coil and the sub-coil in an axial direction thereof is shorter than a length of the other coil in an axial direction thereof, wherein a shift amount of the center position in the axial direction between the main coil and the sub-coil is 12 mm or less, and wherein the leakage inductance is 4.0 μH or less.
