...Sergey E. Zirka; Dennis Albert; Alexander Fröhlich Purpose The work proposes an approach for reproducing in detail the no-load losses and currents of large five-legged transformers when using their transient circuital models. This purpose is achieved by using topological transformer models based...

...Sergey E. Zirka; Dennis Albert; Yuriy I. Moroz; Lukas Daniel Domenig; Robert Schürhuber Purpose This paper aims to propose a method of parametrizing topological transformer model at high flux densities in the core. Design/methodology/approach The approach proposed is based on terminal voltages...

...Sergey E. Zirka; Yuriy I. Moroz; Cesare Mario Arturi Purpose Despite its well-founded criticism and lack of proper justification under core saturation conditions, the T-equivalent transformer model (Steinmetz scheme) is obviously championing in the literature. This educational paper aims...
