METHOD FOR REGULATING SINUSOIDAL VOLTAGE ON LOAD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC G05F1/253 

FIELD: electrical engineering.

SUBSTANCE: used in electrical networks for flexible regulation and stabilization of voltage in the electrical network by changing the magnitude of the voltage introduced in series into the transmission line. The technical result is achieved by the fact that in the method of regulating the sinusoidal voltage on the load by controlling the boost voltage of an alternating voltage regulator containing a multi-winding boost transformer with a network winding included in the branch connecting the input and output terminals, an additional controlled switch connected between the input and output terminals , serial controlled switch, key voltage converter, the input terminals of which are connected to the power source, and the secondary windings of a multi-winding boost transformer are connected to the output terminals, control of the key converter, additional and serial controlled keys is synchronized with the voltage of the power source, connection of the input terminals of the key converter to the source power supply is carried out using control of a serial controlled key, and the change in the mutually opposite states of the additional and serial controlled keys is carried out simultaneously at fixed times relative to the voltage of the power source, while the control of the key converter is implemented in the interval of the off state of the serial controlled key. In the sinusoidal voltage regulation device, the input terminals of the key converter are connected to the input terminals of the power source through a serial controlled switch.

EFFECT: improving the weight and size parameters, increasing efficiency of the device by eliminating the serial switch from the load current flow circuit and reducing losses in the key converter in steady-state operation.
