FIELD: electricity.
SUBSTANCE: three-phase single-phase transformer contains a magnetic circuit, two connected in series primary windings and a secondary winding. The magnetic core is made three-rod. Primary windings are wound on the two extreme rods of the magnetic circuit and are connected in series in a counter-manner. The secondary winding is wound on the middle rod, the width of which is equal to 
times the width of the outer rods.
EFFECT: reduction of weight and dimensions, simplification of design and increase of efficiency.
