Modern promising development directions of alternating current converters plants

Abstract

Relevance: the relevance of the work is explained by the fact that it presents modern development trends in powerful alternating current converters, which are widely used in various industrial production processes, agriculture, and other areas. Today, the most widely used method for creating powerful alternating current converters is the use of double energy conversion systems (DECs). The article presents the electrical scheme and functional tasks of the DECs system, as well as the technical and schematic capabilities of the IKM inverter, its hybrid and matrix structure, and the importance of the effective use of independent (autonomous) filters to improve the harmonic content of the output parameters. The article also shows that the hybrid structure can be used in conjunction with high-harmonic filters to improve the input power factor and eliminate the problems of electromagnetic incompatibility.

Aim: To increase the effective application of various schematic objectives of modern high-power alternating current converters in industrial production, agriculture, and other fields through the use of dual energy conversion systems (DECs).

Methods: the most widely used double energy conversion systems (DECs) and simulation modeling methods were used to create powerful AC converters.

Results: The use of rectifiers with pulse width modulation and harmonic filter in the creation of dual energy converters, which are widely used in various industrial production processes, is explained by the fact that it is possible to improve the input power factor of the device, increase the input power factor of the device, and solve the problem of electromagnetic compatibility that may arise with the network, and the matrix structure of the converter allows you to increase or decrease the output voltage frequency relative to the primary source frequency, while increasing the reliability of the system.
