FIELD: electric engineering.
SUBSTANCE: autonomous supply can be used as autonomous dc supply in electric supply systems of movable communication and control objects. Dc electric energy autonomous supply has internal combustion engine, dc generator, load current detector, electric energy connecting unit, buffer accumulator battery, accumulator batter charge and discharge current detector, unit for controlling fuel supply, unit for controlling current frequency of rotation of crankshaft of engine, voltage adjustment unit, unit for changing voltage of generator at idle stroke, unit for correcting frequency of rotation of engine's crankshaft, unit for controlling modes of operation and engine's starting unit.
EFFECT: improved stability of output voltage of generator at sharp changes in load current; prolonged service life of engine; reduce number of turns of engine; reduced fuel consumption.
