“…These problems are analyzed and (successfully) solved by many authors. In general, it is possible to say that by increasing the efficiency of the equipment, the energy density is also increasing, as well as the demands for optimization of the available energy sources [10,11,[14][15][16][17], with special emphasis on the use of semiconductor elements [18][19][20][21][22][23][24]. However, a comprehensive study that focuses on the issue of a FC with a given practical use, as presented in this article, has been lacking so far.…”

The efficient utilization of energy sources seems to be one of the most challenging problems for designers and scientists alike. This challenge particularly applies to power electronics, where the increasing value of energy density leads to demands for optimization processes and better exploitation (and distribution) of available power sources. As a result, the implementation of frequency-controlled systems is more often in the spotlight. The systems with doubly fed induction machines and a frequency converter in the rotor circuit are typical representatives of these demands. In a wide spectrum of power electronic systems, frequency converters are often used that have a constant current, a diode rectifier, and a thyristor inverter. This article provides a novel approach to modeling methodology, and presents a unique comparison of four different frequency converter schemes that are connected to a doubly fed induction machine. This article presents the modeling methodology itself, as well as the results based on an asynchronous generator motor fed by different frequency converters, a spectral analysis of the output voltage of the used frequency converters, and a comparison of the different technologies. Based on the above, this paper recommends the use of a multistage-multilevel frequency converter scheme.
