A High Power Planar Triode Oscillator Designed by Using FEM Modeling

S. Lefeuvre[1], M. Ghomi[2]
[1]EURL CREAWAVE, Labège, France
[2]CALCEM, Ste Foy d'Aigrefeuille, France

COMSOL, adding SPICE® elements into its FEM, gives the possibility of a direct modeling of oscillators: triode and load are FEM described while all the other components of the circuit are just simulated using SPICE®. The modeling is not a straight application of any module but needs the ... Mehr lesen

Utilization of COMSOL Multiphysics' JAVA API for the Implementation of a Micromagnetic Modeling and Simulation Package with a Customized User Interface

L. Teich[1], A. Hütten[2], C. Schröder[1]
[1]Department of Engineering Sciences and Mathematics, Computational Materials Science & Engineering (CMSE), University of Applied Sciences Bielefeld, Bielefeld, Germany
[2]Department of Physics, Thin Films and Nanostructures, Bielefeld University, Bielefeld, Germany

One of the big advantages of COMSOL Multiphysics is the possibility to implement user-defined partial differential equations (PDE) which can be coupled to COMSOL\'s predefined physics interfaces. However, using the tool’s standard user interface requires manual implementation of the PDEs ... Mehr lesen

Modeling, Simulation, and Control of Dual Electromagnet Active Magnetic Levitation

A.K. Pi?at[1]
[1]AGH University of Science and Technology, Kraków, Poland

Introduction: The dual electromagnet configuration of Active Magnetic Levitation system (AML) where the electromagnets are locate opposite to each other, constitutes and single axis of the Active Magnetic Bearing. The same configuration can be used to test the single electromagnet AML ... Mehr lesen

Numerical Simulation of a Human Body Subjected to Electrostatic Fields for Study of the Turin Shroud Body Image

G. Fanti[1], L. Matordes[1], V. Amoruso[2], M. Bullo[1], F. Lattarulo[2], G. Pesavento[1]
[1]Dip. di Ingegneria Industriale, Università di Padova, Padova, Italy
[2]Politecnico di Bari, Bari, Italy

The TS (Turin Shroud) [1,2] is a fine linen fabric showing a not yet explainable [3] double body image of a scourged and crucified man stabbed on the side. Many hypotheses have been formulated without success [4] and perhaps the most reliable is one correlated to the Corona Discharge [5] ... Mehr lesen

FEM Modeling of Electric Field and Potential Distributions of MV XLPE Cables Containing Void Defect

M. Alsharif[1], P. Wallace[2], D. Hepburn[2], C. Zhou[2]
[1]Department of Physics, Faculty of Arts, Sebha University, Sebha, Libya
[2]School of Engineering & Computing, Glasgow Caledonian University, Glasgow, United Kingdom

Introduction: Failure in cable insulation is generally preceded by a degradation phase that may last several years. A significant cause of cable system failures is the breakdown of electrical insulation between the electrodes. The operational stresses that occur in cable insulation which ... Mehr lesen

Easy Evaluation of Streamer Discharge Criteria

G. Eriksson[1]
[1]ABB, Corporate Research, Västerås, Sweden

An easily implemented method is devised, where analytical criteria for the occurrence of streamer discharges in strong electric fields are evaluated. This is highly useful when designing high voltage power transmission systems and components where the insulation is provided by a gas, e ... Mehr lesen

Electromagnetic Actuators Modeling, Simulation and Optimization
