SELF-CONTAINED POWER SUPPLY SYSTEM Russian patent published in 2013 - IPC H02J9/02 

FIELD: electricity.

SUBSTANCE: device contains a direct current source, a variable resistor, a breaker, a direct current motor, two synchronous generators, a unit of automatic power supply blocking, three-phase rectifier, consuming units and an actuation component; at that the output of direct current source through a variable resistor is connected to the second input of the breaker having the first input connected through the unit of automatic power supply blocking to the output of tree-phase rectifier and having the output connected to the input of direct current motor which is fixed rigidly to the first synchronous generator having the first, second and third outputs connected respectively to the first, second and third inputs of consuming units; in the device there is also a synchronous generator with similar location of excitation windings which is fixed rigidly to the first and second synchronous generator and has the first, second and third outputs connected respectively to the first, second and third inputs of the three-phase rectifier.

EFFECT: rotation of the shaft of a direct-current motor operating from a direct-current source.
