SYSTEM OF AUTONOMOUS ELECTRIC POWER SUPPLY Russian patent published in 2008 - IPC H02P9/02 H02P9/30 

FIELD: electricity.

SUBSTANCE: system of autonomous electric power supply consists of a source of direct current, a rheostat, automatic tripping device, the electric motor of direct current, the synchronous generator with the activator, the unit of automatic adjustment of the feed, the three-phase rectifier with a ripple filter and consumed units. The output of the source of direct current through a rheostat is connected to the second input automatic tripping device, which has the first input and the output accordingly connected to an output of the electric motor of direct current and through the unit of automatic adjustment of a feed - with an output of the three-phase rectifier with a ripple filter. The first, second and third inputs of the three-phase rectifier are accordingly connected to the first, second and third inputs of consumed units, and also with the first, second and third outputs of the synchronous generator with the activator. Electromagnetic coupling is rigidly connected with the electric motor of direct current and with the synchronous generator with the activator and has the input connected to an output second automatic tripping device, which has the first and second inputs connected according to the output of the rheostat and with the output of the block of automatic adjustment of the feed.

EFFECT: increase in the time of constant rotation of the shaft of the electric motor when the direct source of current is disconnected without an increase in the sizes.
