FIELD: autonomous power systems which require stable or adjustable frequency of output voltage with alternating shaft rotation frequency.
SUBSTANCE: in accordance to the invention, a device is introduced additionally which allows to create conditions for self-excitation of generator, and, therefore, to exclude the additional supply of stable frequency excitation current from the circuit.
EFFECT: simplified construction, improved mass and size characteristics, increased reliability of the system.
