Simulation study on rotating radial electromagnetic force for use in dynamic balancing

Yong Li, Yongping Lu

A tentative idea of introducing rotating electromagnetic force for dynamic balancing is presented in the paper. A method of generating the force is put forward, the force…

Fault location in transmission line using hybrid neural network

Stanislaw Osowski, Robert Salat

The paper presents the application of self‐organizing neural network for the location of the fault in the transmission line and estimation of the parameter of the faulty element…

High field mobility and diffusivity of an electron gas in silicon devices

S.F. Liotta, A. Majorana

In this paper we consider the Boltzmann equation describing the carrier transport in a semiconductor. A modified Chapman‐Enskog method is used, in order to find approximate…

Multiobjective shape optimization of air‐cored solenoids

P. Di Barba

The multiobjective optimization of an eight‐block actively‐shielded solenoid has been performed. After a study of each objective function for simplified configurations, up to…

Regenerative motor and plug braking operations of electrical drives for road vehicles

E. Pagano, O. Veneri

The paper suggests a fully digital technique, which may be successfully used for electric drives for road vehicles. The technique is based on the use of a feeding algorithm which…

Mapping full‐systolic arrays for matrix product on XILINX's XC4000(E,EX) FPGAs

A.K. Oudjida, S. Titri, M. Hamerlain

Matrix product is a compute bound problem that can be efficiently handled by elementary systolic algorithms. From a theoretical point of view, most of the algorithms are very…

Harmonic elimination of electric arc furnaces by active power filters and their stability analysis

H. Ghoudjehbaklou, A. Kargar

Three different active power filter (APF) configurations are developed for harmonic elimination of a three‐phase electric arc furnace (EAF). Three single‐phase APF, a three‐wire…

Dynamic discriminant analysis for predictive maintenance of electrical components subjected to stochastic wear

Flavio Allella, Elio Chiodo, Mario Pagano

An optimal maintenance program for electrical power system components should be based on their reliability. Since, for components characterized by high reliability and cost such…

Newton and quasi‐Newton algorithms for non‐linear electromagnetic–thermal coupled problems

Johan Driesen, Kay Hameyer

A general framework for the application of the Newton methods in non‐linear coupled electromagnetic‐thermal problems solved with the FEM on independent subproblem meshes is…

3D edge element analysis of saturation effects in a permanent magnet machine

Andrzej Demenko, Lech Nowak, Wojciech Pietrowski, Dorota Stachowiak

The paper presents a method for the 3D edge element analysis of saturation effects in the classical rotating electrical machines of cylindrical structure. The edge element (EE…

Large‐signal modulation of MQW long‐wavelength lasers

Jorge Manuel Torres Pereira

The large signal modulation response of a 1.3 μm InGaAsP 4‐well laser of the Fabry–Perot type is investigated. The current density is assumed to take the form J = J_O+J_M sin(ωt…

Characterization of spurious‐free finite element methods in electromagnetics

Paolo Fernandes, Mirco Raffetto

From a theoretical point of view the question of spurious modes has been regarded as a closed problem. However, in this paper we show that even a precise definition of…
