SINGLE-PHASE-THREE-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 for production of stabilised transformers with rotary magnetic field. Single-phase-three-phase transformer incorporates two primaries arranged on toroidal part and spaced apart by 90°. The windings inputs are interconnected via a phase-shift capacitor. Three secondaries are arranged on the core spaced apart by 120°. Every primary contains the first and second coil groups made up of four coils laid in 32 slots. The output of the first coil group of every winding 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-shift capacitor, to the input of the second primary. The outputs of the primaries are interconnected and connected to the second output of power supply. Every secondary consists of 12 coils laid in 36 slots.

EFFECT: optimised design of transformers with rotary magnetic field.
