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 …

The trend toward high power density, high operating frequency, and low profile in power
converters has exposed a number of limitations in the use of conventional wire-wound …

Based on an enhanced topological representation of the transformer core, flux air paths, and
tank, a duality-based transformer model is proposed for low and mid-frequency transients …

This two-part paper is intended to clarify definitions in dual transformer modeling that are
vague, provide accurate modeling guidelines, clarify misconceptions about numerical …

A transformer is the most widely used equipment in power systems to transfer energy from
one circuit to another. For real-time electromagnetic transient simulation, this paper presents …

A methodology for the reduction of the residual flux in network transformers is proposed in
this paper. The purpose is the mitigation of large inrush currents taken by numerous …

It is commonly recognized that correct transformer model (particularly topological one) is a
key element for any ferroresonance simulations. This paper represents a line of reasoning …

Ferroresonance leads to a high saturation of the transformer core. This causes severe rise of
the amplitude of current and voltage of the transformer and leads to current and voltage non …

This paper investigates impacts of various formations of hysteresis on the stability domain of
ferroresonance modes of a voltage transformer (VT). Based on four different hysteretic and …

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 …
