Magnetic-Shield-Type Fault Current Limiter Equivalent Circuit

IEEE Transactions on Appiled Superconductivity, 2004
In order to investigate how a superconducting fault current limiter (SFCL) can enhance the performance of a power system, an accurate circuit model of the device needs to be introduced in power system simulators. In this paper, we present a finite-element numerical model to calculate the time evolution of the voltage across a magnetic-shield-type SFCL,

Modeling integrated magnetic gears using a magnetic equivalent circuit

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015
This paper introduces an integrated magnetic gear intended as direct-drive. Next, a magnetic equivalent circuit for the presented gear topology is proposed. This approach uses the principle of virtual work for torque calculation and takes magnetic leakage and saturation into account.

Magnetic Equivalent Circuit Modelling of Synchronous Machines

2023 IEEE International Electric Machines & Drives Conference (IEMDC), 2023
Design of electric machines constitutes a complex and nonlinear problem where the primary design tool is mainly the finite element method (FEM) in the absence of an accurate and easy to implement analytical technique. Although the accuracy of the FEM is high, its adoption within multi-objective optimization is hindered by the high computational burden.

Nonlinear magnetic equivalent circuit of the hybrid magnetic bearing

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2019
Purpose The purpose of this paper is to create a reliable nonlinear magnetic equivalent circuit (NMEC) of the hybrid magnetic bearing (HMB). Commonly used magnetic equivalent circuits of HMB omit a saturation effect of the magnetic material as well as the leakage and fringing flux.

A dynamic equivalent circuit model for solid magnetic cores

Proceedings of IEEE Power Electronics Specialist Conference - PESC '93, 2002
This paper presents a dynamic equivalent circuit model of solid magnetic cores for high frequency operation in power electronic circuits. The effects of eddy current, domain wall motion and hysteresis are taken into account by distributed equivalent resistors and distributed nonideal differential inductors, respectively.

An Analytical Method Combining Equivalent Circuit and Magnetic Circuit for BDFRG

IEEE Transactions on Magnetics, 2014
This paper presents an analytical method that integrates the equivalent circuit (EC) and magnetic circuit (MC) in order to analyze and design a brushless doubly fed reluctance generator (BDFRG). The proposed method is capable of evaluating the BDFRG performance at the design stage because the terminal voltage can be predicted through the MC and the ...

Magnetic Equivalent Circuit Modeling of Induction Motors

IEEE Transactions on Energy Conversion, 2007
Finite element models are invaluable for determining expected machine performance. However, finite element analysis can be computationally intense; particularly if a large numbers of studies or high bandwidth studies are required. One method to avoid this difficulty is to extract machine parameters from the finite element model and use the parameters ...

Dual Equivalent of Magnetic Circuits with Hysteresis

2007 Compatibility in Power Electronics, 2007
A representation of magnetic circuits with a topological dual equivalent circuits is presented. The dual equivalent circuit consists of permeance elements instead of reluctances and includes the modelling of hysteresis nonlinearity and iron losses. The hysteretic permeances in the dual magnetic circuit are modelled with the Jiles-Atherton (JA) approach

Magnetic equivalent circuit of synchronous reluctance machine

2016 ELEKTRO, 2016
Finite element method (FEM) is a powerful tool in analysis of electrical machines however, the computational cost is high depending on the geometry of analyzed machine. In synchronous reluctance machines (SyRM) with transversally laminated rotors, the anisotropy of magnetic circuit is provided by flux barriers which can be of various shapes.
