Abstract

A low-loss reactor (1) is made up of a core having a coil (5), said core comprising an upper and a lower yoke (2, 3) and intermediary legs (4a, 4b, 4c). The two yokes and the legs are made up of laminations of plates, said laminations in at least one of the yokes consisting of non-directionally oriented plates. The laminations in the remaining yoke and legs consist of rolled plates of ferro-magnetic material having a magnetic preference direction.
