Abstract (en)

The invention is related to a voltage-regulation-transformer (10), comprising a transformer core (40) and a first group (12, 72) of three hollow cylindrical coils (14, 16, 18), wherein the transformer core (40) comprises three parallel limbs (54, 56, 58) extending along three parallel limb axis (34, 36, 38), wherein the transformer core (40) comprises a first (42) and a second (46) parallel yoke section connecting the respective first and the respective second ends of the limbs (54, 56, 58) and wherein each coil (14, 16, 18) of the first group (12, 72) is arranged around a respective limb (54, 56, 58). The transformer core (40) comprises three further limbs (60, 62, 64) that's respective first ends are connected with the second yoke section (46) and that's respective second ends are connected with a third yoke section (50), which is arranged in parallel to the first (42) and second (46) yoke section and a second group (20, 78) of three hollow cylindrical coils (22, 24, 26) is foreseen, wherein each coil of the second group is arranged around one of the respective further limbs (60, 62, 64).
