ABSTRACT:
Ferromagnetic cores and electric transformers having a ferromagnetic core having at least two ferromagnetic circuits are described. At least one ferromagnetic circuit is composed of a ferromagnetic amorphous material and at least one ferromagnetic circuit is composed of a grain oriented electrical steel. The amorphous material having a saturation induction which is lower than that of the grain oriented steel. Methods of fabricating the core and using the transformer are also described.
