SINGLE-PHASE-SINGLE-PHASE TRANSFORMER WITH ROTARY MAGNETIC FIELD Russian patent published in 2008 - IPC H01F30/14 H02M5/14 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in production of stabilised transformers with rotary magnetic field. The single-phase-single-phase transformer incorporates two primaries arranged on toroidal part spaced apart by 90°. The primaries inputs are interconnected via a phase-shifter capacitor. One secondary is arranged on the core along the diagonal of the elliptic rotary magnetic field induced by the primaries. Every of the concentric primaries contains the first and second coil group made up of three coils laid in 24 slots. The output of the first coil group of every coil is connected to the output of the second coil group. The input of the first primary is connected to the power source first output and, via the phase shifter capacitor, to the second primary input. The outputs of primaries are interconnected and wired to the power source second output. The secondary has two coils groups made up of 8 coils laid in 16 of 24 slots. The first coil group output is connected to the second coil group output. The first coil group input and the second coil group output make the outputs of transformer with the rotary magnetic field for the load to be connected thereto.

EFFECT: output voltage stabilisation by varying phase shifter capacitor capacity.
