Abstract

The relevance of this work is explained by the presentation of modern trends in the development of powerful AC converters, which are widely used in various industrial processes, agriculture, and other sectors. Today, the most widely used method for creating powerful AC converters is the use of double energy conversion systems (DECS). The article shows the electrical diagram and functional tasks of the DECS system, as well as the technical and schematic capabilities of the pulse width modulation (PWM) inverter.  It highlights the importance of effectively using independent (autonomous) filters to improve the hybrid and matrix structure, as well as the harmonic composition of output parameters. The article also demonstrates that by using a hybrid structure in conjunction with high-harmonic filters, it is possible to increase the input power factor and eliminate problems of electromagnetic incompatibility. To increase the level of effective application of modern high-power AC converters in industrial production, agriculture, and other areas through the use of double energy conversion systems. The methods of applying double energy conversion systems and simulation modeling, which are most widely used in the creation of powerful variable frequency drives, were utilized. The use of pulse width modulation and harmonic-eliminating filtered rectifiers in the creation of dual-energy conversion devices, widely used in various industrial production processes, allows for improving the device's input power factor, increasing the device's power efficiency, and solving potential electromagnetic compatibility issues with the network. Additionally, the matrix structure of the converter enables increasing or decreasing the output voltage frequency relative to the primary source frequency, while simultaneously improving the system's reliability.
