Numerical solutions of a viscous‐hydrodynamic model for semiconductors: the supersonic case
Luca Ballestra, Fausto SaleriIn this paper, we solve by a finite difference upwinded method an extended hydrodynamic model for semiconductors, with viscous terms in the momentum equation. In particular, we…
Fixed‐point technique in computing nonlinear eddy current problems
Wieslaw PetersonEddy currents are investigated in a ferromagnetic bar exposed to a transverse magnetic field. Such an open boundary field problem is analysed applying the Galerkin finite element…
Modelling and simulation with neural and fuzzy‐neural networks of switched circuits
Yakup Demir, Ayşegül UçarRecently, the modelling and simulation of switched systems containing new nonlinear components in electronics and power electronics industry have gained importance. In this paper…
Fourier analysis of hysteretic distortions
Jenö TakácsThe paper presents the derivation of the Fourier coefficients of the magnetisation wave form in closed form for periodic triangular field excitation. The mathematical model used…
Electromechanical properties of a disc‐type salient‐pole brushless DC motor with different pole numbers
Marian Lukaniszyn, Mariusz Jagiela, Rafal WrobelA brushless, permanent magnet, three‐phase disc‐type salient‐pole DC motor with co‐axial flux in the stator is considered. Electromechanical properties of a basic eight‐pole motor…
Use and analysis of null flux coils
Kent R. DaveyThere are a number of ways to maintain stable levitation and guidance in Maglev through induction. If the secondary currents are unconstrained, the lift to drag ratio is much less…
Stochastic response surface method and tolerance analysis in microelectronics
Angelo Marcello Anile, Salvatore Spinella, Salvatore RinaudoTolerance analysis is a very important tool for chip design in the microelectronics industry. The usual method for tolerance analysis is Monte Carlo simulation, which, however, is…
Evaluation of hysteresis loss using variable pinning parameter
Zdzislaw Wlodarski, Jadwiga WlodarskaThe Jiles‐Atherton model of magnetization gives a general description of magnetic induction and hysteresis loss against magnetic field and corresponding current. At wider regions…
Field‐circuit analysis of construction modifications of a torus‐type PMDC motor
Marian Lukaniszyn, Rafal Wrobe, Mariusz JagielaThis paper presents the field‐circuit analysis of a disc‐type torus DC motor with permanent magnets. Calculations of the magnetic field are carried out using the finite element…
New approach to the optimisation of three‐phase three‐wire systems with sinusoidal voltage sources and nonlinear loads
Pasko Marian, Debowski KrzysztofThe problems presented in the paper deal with the three‐phase three‐wire system with sinusoidal voltage sources and nonlinear loads. In the model of the three‐phase voltage source…
Probabilistic approach to series compensation design
Flavio Allella, Elio Chiodo, Davide LauriaSeries capacitive compensation in electrical power systems is generally recognized as a very economical and powerful means for increasing the transmission capability of…
Category, slot harmonics and the torque of induction machines
Jan RusekBased on Fourier series theory, for almost periodic functions, the general as well as the specific harmonic‐balance model of induction machines is presented together with a brief…
Stability analysis of the doubly fed machine with emphasis on saturation effects
Ahmed MasmoudiThe doubly fed machine (DFM) is presently given an increasing attention in high power variable speed drives and in wind power generation systems, where it exhibits high…
Simulations of bilateral energy markets using MATLAB
Y.S.C. Yuen, K.L. LoThis paper presents simulation results of energy bilateral markets using MATLAB/SIMULINK. The algorithm for congestion management and transmission pricing is implemented by means…
