A Numerical Approach for the Mechanical Analysis of Superconducting Rutherford-Type Cables Using Bimetallic Description

Low-temperature superconductors are widely used in high-field magnets, mostly within Rutherford-type cables. The run for higher fields leads to greater forces on the conductor, which is pushed closer to its mechanical limit. Managing the higher…

Impact of thermal stress on the ageing behaviour of aluminum electrolytic capacitors for automotive applications

DC link filter capacitors used in electric drives for automotive applications are most of the time aluminum electrolytic capacitors. However their high sensitivity to temperature results in very weak components. So, a lot of studies have been made…

Robust Calibration of Radio Interferometers in Non-Gaussian Environment

The development of new phased array systems in radio astronomy, as the low frequency array (LOFAR) and the square kilometre array (SKA), formed of a large number of small and flexible elementary antennas, has led to significant challenges. Among…

Mechanisms of power module source metal degradation during electro-thermal aging

The long-term reliability of power devices for applications in the automotive industry is limited by the electro-thermal and/or thermo-mechanical aging of the metallic parts. In the present work, we characterize the bonding wire and source…

Characterization process to measure the electrical contact resistance of Gas Diffusion Layers under mechanical static compressive loads

Recent research has identified the mechanical properties of the fuel cell internal components (in particular, the Gas Diffusion Layers - GDLs) as key-parameters to obtain high final performances of the generator. The mechanical compression modulus…

Overall Size Optimization of a High-Speed Starter Using a Quasi-Z-Source Inverter

In new generation of more electric aircrafts, dc-bus voltage is variable due to the variable speed generator. This implies constrains to design the actuator for the lowest dc voltage value. In case of permanent magnet synchronous machine (PMSM)…
