Abstract: A hybrid transformer core includes a first yoke of amorphous steel and a second yoke of amorphous steel. The hybrid transformer core further includes at least two limbs of grain-oriented steel extending between the first yoke and the second yoke. The first end of each one of the at least two limbs is coupled to a first surface of the first yoke in a first connection plane and wherein a second end of each one of the at least two limbs is coupled to a second surface of the second yoke in a second connection plane. The first surface in all directions along the first connection plane extends beyond the first end of each one of the at least two limbs. The second surface in all directions along the second connection plane extends beyond the second end of each one of the at least two limbs.
