With the fast-paced changing technologies in the power industry, new references
addressing new technologies are coming to the market. Based on this fact, there is an urgent …

Transformer design is a complex task in which engineers have to ensure that compatibility
with the imposed specifications is met, while keeping manufacturing costs low. Moreover …

Monopole HVDC systems create dc current flow in the earth, which can cause the grounding
location potential to rise relative to infinite spot and alters the working point of the …

In this paper, a three-phase transformer model is developed to be suitable for slow transient
and power-quality studies. The proposed model takes into account the eddy currents, the …

This article presents the modified Preisach model of hysteresis for a 3-phase medium
frequency transformer in a 100 kW dual active bridge converter. The transformer magnetic …

Abnormal vibration may cause the internal failure of transformers. In particular, the nonlinear
saturation vibration of the iron core under direct current (DC) magnetic bias will lead to …

This paper deals with the differential evolution (DE)-based method for determining the
magnetically nonlinear iron core characteristics of transformers and iron core inductors. The …

This article proposes an innovative methodology to estimate the saturation curve of three-
phase three-legged transformers, including deep saturation. Unlike other methodologies …

This article presents a nonlinear equivalent circuit model of an isolated dc-dc converter with
a 3-phase medium frequency transformer. The model takes into account the magnetic cross …

Accurate modeling of three-phase asymmetric (three-and five-limb) transformers is still a
challenge. In this paper, a method for the calculation of the major hysteresis loop for three …
