Highly efficient bidirectional Silicon Carbide power converter for Electric Vehicle flywheel emulator

Flywheels are nowadays a solution for the dynamic charging of electric vehicles since they act as transient energy storage. The need of a top efficient reversible power converter for the flywheel system is crucial to assure high dynamic performance…

Influence of plastic compression on the magnetic behaviour of a pipeline steel

Sensitivity of magnetic behaviour to plastic deformations is only documented in literature for uniaxial tensile testing and few models claim to take into account the plastic deformation sign. We present in this paper some new results showing the…

Analyse thermique à haute résolution spatiale par thermoréflectance de composants de puissance

The technological evolution of IGBT components requires a strong increase in power density. This increase in power density leads to very high temperature fields and gradients in the components and makes it necessary to know the thermal constraints…

Diagnosis of PEMFC based on autoregressive model and voltage fluctuation

A novel diagnosis approach for proton exchange membrane fuel cell (PEMFC) systems is proposed in this paper. Different fault conditions can be classified based on the patterns of stack voltage fluctuation, which can be extracted by the…

Robust design optimization taking into account manufacturing uncertainties of a permanent magnet assisted synchronous reluctance motor

In this paper, deterministic and robust design optimizations of a permanent magnet assisted synchronous reluctance machine were performed to increase its mean torque while reducing torque ripple. These optimizations were carried out using a…
