Abstract
In this paper, a new three-phase-to-four-phase transformer with four-phase four-leg structure is first proposed, its electromagnetism principle is analyzed, and the properties and features of the transformer are also discussed. This transformer may be applicable to either four-phase transmission systems or autotransformer (AT) traction power-supply systems in electric railways.
