Transformers often encounter electromagnetic transients, such as ferromagnetic resonance
and inrush currents. An accurate low-frequency modeling of transformers is essential for …

An equivalent circuit model for planar printed circuit board (PCB) transformers is presented.
The model utilizes the 1-D analysis of Maxwell's equations to develop a frequency …

The differential evolution (DE) algorithm belongs to a class of evolutionary techniques that
use the stochastic approach to solve optimization problems. Storn and Price proposed it in …

The aim of the present paper is to validate the Bouc–Wen (BW) hysteresis model when it is
applied to predict dynamic ferromagnetic loops. Indeed, although the Bouc–Wen model has …

The modelling of the dynamic behavior of hysteretic materials and devices must take into
account magnetodynamic effects. In the present paper these tasks are simultaneously …

When power transformers are re-energized, the inrush current may be generated and
damage electrical equipment. In order to suppress the generation of serious inrush current …

This paper deals with the fundamental theoretical background of a 1-D parametric magneto-
dynamic (PMD) model, which analytically solves the interdependence of the magnetic field …

The inrush current causes many adverse effects on electrical equipment. One of the reasons
for inrush current is residual flux. When a no-load transformer is energized and the closing …
