FIELD: information technology.

SUBSTANCE: present invention relates to electrical engineering. The proposed device is provided with voltage source regulators, with the same number of input terminals for each regulator. The device contains the same number of groups of coils of first and second differential inductive current sensors, as well as the same number of parallel operation transformers, as there are input terminals at each regulator. Each of the coils in any group of coils of the first and second differential sensors is inductively coupled with one of those load current conducting wires of the above mentioned voltage sources, which are connected between similar terminals of these sources and one of the common buses, to which is connected the load. The coils of the first and second differential inductive current sensors, inductively coupled with the load current conducting wires of any of the sources, form a set of coils for all groups, and each parallel operation transformer is connected to coils of only one group and has the same number of turns on all windings. Mutual inductance of all coils of the first and second differential inductive current sensors with load current conducting wires has values inversely proportional to nominal current of voltage sources. Terminals of the primary windings of the parallel operation transformers are connected to leads of the coils of the first differential inductive current sensors, related to the driving voltage source, and secondary windings of any parallel operation transformer are connected between input terminals of voltage source regulators and the beginning of those coils of second differential inductive current sensors, which are inductively coupled with current conducting wires of these sources. The ends of these coils are connected to output terminals of these voltage sources, to which are connected the said current conducting wires. Also there are is the same number of extra sets of coils of differential inductive current sensors, as there are parallel connected voltage sources. Each one of them is provided with one set of coils of first differential inductive current sensors and one set of coils of second differential current sensors, as well as a switch, closing contacts of which are connected in parallel to terminals of the primary windings of parallel operation transformers. All input terminals of voltage regulators of all driven and driving sources are connected to corresponding output terminals of sources through the given circuits, containing secondary windings of parallel operation transformers and coils of second differential inductive current sensors.

EFFECT: possibility of converting a driven source into discharge of driving source and driving source into discharge of driven source without disconnecting the load, while cutting on time for carrying out these operations; reduced mass and size of the device.
