Abstract
A multi-phase reactor is configured to include a first core arranged at a center of the reactor; a plurality of second cores provided outside the first core and arranged so that each of magnetic paths with respect to the first core is in a loop shape; and one or a plurality of windings wound around each of the second cores. With this configuration, the multi-phase reactor capable of setting a constant value of inductance for each phase is provided.

A multi-phase reactor comprising:
- a first core arranged at a center of the reactor;
- a plurality of second cores provided outside the first core and arranged so that each of magnetic paths with respect to the first core is in a loop shape;
- and
- one or a plurality of windings wound around each of the second cores, wherein
- each of the second cores includes two end portions opposite to the outside of the first core, the two end portions being located at different positions along the outside of the first core without contact between the two end portions and the outside of the first core.
