SINGLE-PHASE TRANSFORMER Russian patent published in 2013 - IPC H01F30/10 H01F30/04 H01F27/42 

FIELD: electricity.

SUBSTANCE: method is implemented by means of use of magnetic conductor with yokes rounded radially its windows; use in the secondary chain instead of one winding designed for certain voltage (current), three windings interrelated due to certain dependence by their inductance; introduction of secondary windings of phase-shifting chain in the scheme. Magnetic conductor with yokes rounded radially its windows, in spite of elongation of the middle line increases transformer efficiency. Introduction of two additional windings in the secondary chain instead of one phase-shifting chain stabilises magnetic induction in function of magnetic field intensity - regardless load value - and thus current phase opposition in primary and secondary windings is provided.

EFFECT: providing minimum losses in transformer during conversion of one voltage variable by value to another one and increasing efficiency.
