TRANSFORMER Russian patent published in 1997 - IPC

FIELD: electric engineering. SUBSTANCE: magnetic circuit 1 is designed as tori 3 with teeth 5 and 6 which are cut on side of face chamber. Coils 7 with windings 2 are mounted on teeth 5. Teeth 6 are used as yokes. Claims of invention describe device design with different shapes of teeth 5 and 6. Tori 4 are inserted to cylindrical glasses or have threads and are mounted for relative movement in radial or axial chambers. This results in possibility to vary output voltage. EFFECT: increased functional capabilities. 7 cl, 12 dwg
