A observação do fenômeno ferromagnético tem sua origem, talvez, alguns séculos antes de
Cristo, na Grécia antiga, em uma região chamada Magnésia (pertencente à “Graecia …

This dissertation addresses technologies and modeling of integrated EMI filters. Suitable
integration technologies are developed, which include reducing the equivalent series …

Dynamic high-fidelity magnetic equivalent circuits (HFMEC) are viable tool for accurate,
physics-based modeling of magnetic components. However, such model formulation …

The goal of this work is to develop an efficient numerical model of foil‐type windings. An
equivalent lumped‐parameter circuit model is presented, which is suitable for the …

A model of a 200 kVA, 240 V to 11 kV, 3 phase power distribution transformer is presented.
1000 impedance measurements, covering a frequency range of 50Hz to 5 MHz were made …

In conventional finite element simulations, foil windings with a thin foil and many turns
require many mesh elements. This renders models quickly computationally infeasible. With …

This dissertation addresses the seemingly inevitable compromise between modeling fidelity
and simulation speed in power electronics. Higher-order effects are considered at the …

In this paper, the authors present a method to synthesize a power autotransformer model
that takes into account high-frequency effects. The proposed procedure implements data …

This paper presents an analysis of the bibliography on transformers covering the period from
1990 to 2000. It contains all the transformer subjects: a) Transformer design, b) Transformer …

The large number of turns in foil windings and the small thickness of the foil require many
mesh elements in conventional finite element simulations. This renders models quickly …
