FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be implemented in the form of a device installed at the input of equipment that needs to neutralize the effect of drawdowns and power surges on the supply network through accurate and smooth adjustment of the alternating voltage. Essence of the invention is that the booster transformer of the dynamic stress compensator is configured to operate in at least two operating modes. In one of them at least one high voltage winding is connected to a controlled inverter, and the other winding or group of windings is connected in series to the network between the current source and the consumer. In the second of the possible operating modes, the low-voltage windings of the booster transformer, re-commutated by means of at least one controllable switching device, are connected to the electrical circuit with the possibility of providing the operation of the booster transformer without connection to the mains, at that the inverter is connected to a power storage and transmission link with the possibility of supplying a booster transformer.
EFFECT: technical result consists in simplifying the design of the device, improving the quality of power supply to the consumer, as well as reducing financial and technological losses by maintaining voltage on the load for at least 1 second in the absence of input voltage, that makes it possible to transfer consumers to the reserve power line.
