Abstract: An adjustable impedance regulating transformer of the type having four windings including a primary winding, a secondary winding and two control windings wound on four legs of a transformer core. The core comprises in sequence a first leg of a first cross section, two legs of twice the first cross section and a fourth leg of the first cross section. The two control windings are located on the two legs of first cross section and the primary and secondary windings are located, respectively, on the two legs of twice the first cross section. The core can utilize standard transformer laminations.
