Comparison of experimentally and by the finite element method determined magnetically nonlinear iron core characteristics applied in the dynamic model of a single phase transformer
Sebastijan Seme, Gorazd Štumberger, 2013, izvirni znanstveni članek

Opis: This paper deals with comparison of experimentally and by the finite element method determined magnetically nonlinear iron core characteristics. The obtained characteristic were used in the dynamic model of a single phase transformer. The comparison of the measured and by the dynamic model calculated results is given for the case of transformer steady state operation at rated load and for the case of switch-on of unloaded transformer.

Impact of saturation modelling on the losses of electric drive controlled by QFT
Dalibor Igrec, Bojan Štumberger, Amor Chowdhury, Miralem Hadžiselimović, 2013, izvirni znanstveni članek

Opis: The aim of this paper is to present the impact of magnetic nonlinearities and saturation on the losses of an electric drive controlled by Quantitative Feedback Theory. For exact analysis of losses three magnetically different types of series wound DC motor dynamic models are presented and used in this work. As its main contribution this study shows that the modelling of magnetic nonlinearities improves control synthesis of electrical drive, which is reflected in lower energy consumption. For the purpose of control design of series wound DC motor Quantitative Feedback Theory was used.
