Abstract

Either a reactor or a transformer comprises two facing yoke iron cores and a plurality of magnetic support iron cores around which coils are wound and gap adjustment means are disposed. The two facing yoke iron cores are connected with the plurality of magnetic support iron cores and are provided with isotropic magnetic bodies on at least one of the connection parts with said isotropic magnetic bodies being formed from an isotropic magnetic material. A power conversion apparatus further comprises either the reactor or the transformer.
