Energy efficiency and harvest, speed and performance, flexibility and portability are key elements for innovation in the current consumer electronics markets. Thermoelectric Generators can convert energy from heat gradients into electricity. Every source of heat from an electronics device can potentially be used as a source of energy. This generators have the advantage of: being silent, compact, ...

An electrostatic headphone includes many interrelated design elements that affect the frequency response of the headphone and the users listening experience. Xi Engineering Consultants (XI) partnered with Warwick Audio Technologies (WAT) to investigate the complex behavior of one-side electrostatic speakers. Xi developed a GUI that helped WAT engineers optimize their speaker using virtual tools ...

Fault Current Limiters (FCLs) are expected to play an important role in the protection of future power systems due to the rising levels of the short-circuit currents. The inductive FCLs, comprising magnetic cores and one or more dc and ac windings, are particularly interesting because they inherently react on the fault. The so-called open-core FCL configuration employs only one magnetic core for ...

This paper presents the Finite Element Method technique for predicting performance of Induction motor having Electric and Magnetic asymmetry for rotor cage due to some broken rotor bars. The motor parameters like magnetic vector potential, flux density, surface currents have been determined very precisely by carrying out two dimensional quasi static, transient analysis and by using one of the ...

The need for high storage capacitors led to the development of polymer based capacitors. Polymers have high processability, mechanical flexibility, electrical breakdown strength and compatibility with printed circuit board (PCB) technologies; but usually have very low permittivity (K). In COMSOL Multiphysics software, the AC/DC module is selected and the In-plane electric currents are applied ...
Using the Electrical Field Analysis for Assessment of the Influence of Paper Insulation on Discharge Initiation in Oil

Conclusions about the influence of paper insulation on the electrical discharge initiation in mineral oil may be drawn on the basis of experimental studies. However, in some cases, these conclusions may be supported by electrical field analysis. Determination of maximum values of electrical field stress in the vicinity of model electrode setups may bring a new information about initiation ...

Research at Fraunhofer EMI addresses the response of materials in extreme dynamic loads. Besides mechanical or thermal loads, intense electric pulse currents also represent an extreme dynamic load. Experimentally, metallic samples, mainly thick wires, were electro-mechanically loaded with currents up to 400 kA. For this purpose, a test rig containing a high-voltage pulsed power supply and high ...

This paper is an investigation into the effect of blood vessel movement on measurement accuracy of blood flow rate using magnetic flow meters. The investigation used a Finite Element model of the magnetic flowmeter built using COMSOL Multiphysics® software by integrating the modules of laminar fluid (blood) flow, electric and magnetic field and structural dynamics (FSI), to mimic performance of ...

This paper presents an analysis approach of multicondcutor quasi-TEM lines transmission interconnect in a single dielectric region and multimode waveguides using the finite element method (FEM). FEM is especially suitable and effective for the computation of electromagnetic fields in strongly inhomogeneous media. We illustrate that FEM is suitable and effective as other methods for modeling of ...

The loaded underground high voltage cable generates magnetic field with industrial frequency. Depending on the current rating and cable allocation, the magnetic exposure to public area may exceed the requested limit from customer. Extra shielding should then be applied. A primary FEM study shows that aluminum plate has a good shielding effect; the installation condition of the plate can however ...
