Asymmetrical magnetization in three-phase core type transformers
(1995-12-01)
The performance of the three-phase core type transformers, under AC/DC double excitation is discussed in this work. It is presented a mathematical model that considers the mutual coupling between phases and the magnetic ...

Vortex-type solutions to a magnetic nonlinear Choquard equation
(Springer, 2015)
We consider the stationary nonlinear magnetic Choquard equation where is a magnetic potential and is a bounded electric potential. For a given group of linear isometries of , we assume that A(gx) = gA(x) and W(gx) = W(x) ...
Galerkin Method and Weighting Functions Applied to Nonlinear H(infinity) Control with Output Feedback
(SAGE PUBLICATIONS LTD, 2010)
This paper considers two aspects of the nonlinear H(infinity) control problem: the use of weighting functions for performance and robustness improvement, as in the linear case, and the development of a successive Galerkin ...
Influence of double excitation AC/DC in the reactive power demand of 3-phase transformers
(IEEE, 1999-12-01)
In this work it is discussed the performance of the reactive power demand in three-leg transformer core and three-phase transformer bank, under different conditions of AC/DC double excitation. In order to analyse the ...
Transport of localized and extended excitations in a nonlinear Anderson model
(1998)
We study the propagation of electrons (or excitations) through a one-dimensional tight-binding chain in the simultaneous presence of nonlinearity and diagonal disorder. The evolution of the system is given by a disordered ...
Modelos não lineares de materiais magnéticos para dispositivos elétromagnéticos
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2016-11-21)
Cores made with magnetic materials are broadly use in several areas of application Electrical Engineering, such as electrical machines and power electronics. Analyzing systems containing these magnetic cores is complex due ...
Realistic cyclic magnetic universe

On a non-ideal magnetic levitation system: nonlinear dynamical behavior and energy harvesting analyses
(Springer, 2019-03-01)
Nowadays, a novelty of devices that use magnetic restoring forces to generate oscillations has increased substantially. These kinds of devices have been commonly used to energy harvesting area. Therefore, in this paper, ...
