ELECTROMECHANICAL DEVICE Russian patent published in 2012 - IPC H02P9/02 H02P9/10 

FIELD: electricity.

SUBSTANCE: output of DC source is connected through rheostat to the first input of automatic release mechanism having the second input connected to output of three-phase rectifier with stabiliser the inputs of which are connected to outputs of synchronous generator. Output of automatic release mechanism is connected to input of DC motor rigidly attached to synchronous generator with exciter. Automatic release mechanism is actuated at equality of voltages. Potentiometer is installed between the second input of automatic release mechanism and output of three-phase rectifier with stabiliser. At that, rheostat output is connected to input of DC motor.

EFFECT: providing load increase without increasing the power of DC source.
