Abstract

To realize an AC circuit which has no voltage and requires no ground-return circuit, in a single-phase transformer, the primary side is constituted by a single-winding coil, and the secondary side is coupled to the primary side by a magnetic circuit and is formed from two coils, one of which is constituted of wire wound clockwise and the other of wire wound counter-clockwise. In a three-phase transformer, the primary side is formed by coils in a star or delta connection, and the secondary side is coupled to the primary side by a magnetic circuit, and each phase is provided with two coils, one of which is constituted by wire wound clockwise and the other of wound counterclockwise, thereby realizing a current circuit on the primary side.
