ELECTRIC POWER SUPPLY Russian patent published in 1999 - IPC

FIELD: electrical engineering, in particular, electrical machines. SUBSTANCE: device has generator with permanent magnets and stepping up generator, which is designed using permanent magnets. Winding of armature of stepping up generator is connected in series to winding of armature of main generator. Shift angle between electromotive force of main generator and that of stepping up generator is close to 180 electric degrees. This results in possibility to use disturbance-compensating control. Output precision of output voltage stabilization is provide by bias winding which embraces stem of armature of stepping up generator. Power supply of bias winding is provided by voltage regulation unit. EFFECT: increased precision of voltage stabilization in complete range of load alteration, complete use of magnet energy. 1 dwg
