The present application discloses a three-phase reactor, including: an upper yoke and a lower yoke, the upper yoke and the lower yoke containing a first material; and at least three first core columns, the first core columns containing a second material, and the both ends of each of the first core columns being connected with the upper yoke and the lower yoke, respectively, wherein, the relative permeability of the first material is greater than that of the second material, and at least one air gap is positioned in each of the first core columns. In the three-phase reactor proposed by the present disclosure, the yokes are made of a material different from that of the core columns, and air gaps are positioned in the core columns, so that the eddy current losses may be reduced significantly and the requirement for the use of high power may be satisfied.
