“…However, it should be noted that the research of circuit topologies of individual stages of the mentioned concept is constantly improving and being perfected. Our discussion concerns a circuit solution, but also a technological one, specifically in terms of the production of semiconductor elements or magnetic components [6][7][8][9]. If we now focus specifically on circuit solutions, we will deal in more detail with the possibilities of solving the input element, i.e., the PFC converter.…”

This paper evaluates the performance of the high-voltage wide-band gap SiC power transistors equipped within 3-phase bridgeless 3 kW PFC circuit. The main aim of the study is the experimental evaluation of the dynamic properties and driving power requirements of the transistors, for which the parameters are similar. These are competing products from different manufacturers, while the selection criterion was the same type of package technology (7 pin D2PAK). Second, the effect of the transistor type was analysed in terms of the performance efficiency of the PFC circuit. Within the analysis, the driver circuit was constructed first, and adapted to high voltage transistor driving. During individual measurements, the driver remained the same, while gate-driver losses were analysed for individual transistors. The obtained results reveal differences related to requirements on driving power, as well as to the dynamics of transistors themselves. At the end of the paper, the evaluation of efficiency for different operating conditions of a constructed PFC converter is realized. The obtained results provide a more detailed overview of the dynamic properties of transistors and their impact on the resulting efficiency of the main circuit also in terms of driving requirements.

“…Several disturbances and nonlinearities affect the tension control system. For this reason, selecting the right type of controller for the system and tuning the controller is not a straightforward operation [23]. In practice, tension control systems are subject to process uncertainties, such as eccentricity of the rolls, misalignment of rolls, or sliding between the strip and rolls [10].…”

The control of tension in processing lines for metal strips tackles several problems. The process of achieving high tension driven by a multi-motor drive system, where the motors are mechanically coupled by a strip, is affected by the maximal torque of each drive, by friction between the strip and the surface of the tension roll, and by the wrap angle. The friction itself and the wrap angle are described by the e µα factor, which can be also calculated as the ratio of tensions in the strip in the previous section and subsequent section of the multi-motor drive. In this paper, an algorithm for the proper distribution of tensions in the strip for a multi-motor drive system of a continuous processing line is revealed. The algorithm ensures the tension distribution among particular drives of the tension leveler while respecting the physical limits of the drives and also preserving the desired conditions of a constant ratio between the input and output tensions for all drives in the leveler. The algorithm also prevents overloading of the drives. Finally, the algorithm was implemented in a control system of a strip processing line, and the obtained results correspond with the simulations. This, in turn, confirms the correctness of the algorithm design.
