Abstract
A transformer apparatus for an electrical power transformation system is provided. The transformer apparatus comprises three outer transformer limbs, an inner transformer limb a transfer star, and first and second connection portions. The transfer star comprises an electromagnetic transfer core and three transfer coils. The electromagnetic transfer core extends from the inner transformer limb to each of the three outer transformer limbs at a point on each outer transformer limb between the first coil assembly and the second coil assembly. The transfer coils are wound around the electromagnetic transfer core such that each transfer coil is arranged between the inner transformer limb and a respective outer transformer limb. The transfer star is configured to allow transfer of magnetomotive force between the outer transformer limbs and the inner transformer limb of the transformer apparatus. First and second connecting portions are to allow magnetic flux to flow between the inner and outer transformer limbs.
