Harmonic and Transient Magnetic Analysis of Single Turn Coils fed by a Current Pulse at Medium Frequency

O. Maloberti [1], O. Mansouri [1], D. Jouaffre [2], D. Haye [2]
[1] ESIEE Amiens, France
[2] PFT Innovaltech, France

Single turn coils are used in pulsed magnetic technologies for which both magneto-harmonic and transient magnetic analysis are required. We suggest studying one single turn coil example made of a conducting massive coil, an optional conducting field shaper and an internal conducting tube ... Per saperne di più

Thermoelectric Generators can convert energy from heat gradients into electricity. Every source of heat from an electronics ... Per saperne di più

FEM Modeling in Robust Design for Graphene-Based Electromagnetic Shielding

S. Elia [1], G. Granata [1], P. Lamberti [1], V. Tucci [1],
[1] University Of Salerno, Italy

Electromagnetic shielding design is usually approached referring to nominal values of the main parameters. This could lead to malfunctioning devices and its performance differ widely from what was really aimed at or, worse, the final design product could even be physically unrealizable. ...

Creep Deformation Behavior of Heating Filaments in High Temperature Applications

B. Valentini [1],
[1] Plansee SE, Reutte, Austria

Resistive heating filaments used in high temperature applications at 2000°C and above are often made of refractory metals. The lifetime of such filaments is mainly limited by creep deformations which can in the worst case lead to a short circuit between filaments and other furnace ... Per saperne di più
