Hysteresis modelling of a medium frequency single-phase transformer
The article describes a feedback Preisach hysteresis model equivalent circuit implementation of a medium frequency single-phase transformer being a part of a high power and high efficiency DC-DC converter.
EPF 2017 “Influence of size distribution […] high voltage epoxy insulators”
Epoxy resins crosslinked with acid anhydride hardeners are widely used in high voltage insulation. They have excellent dielectric, electrical and mechanical properties up to relatively high temperatures. However, neat epoxy systems exhibit low thermal conductivity and unsuitable coefficient of thermal expansion (CTE) when used with metallic materials such as high voltage conductors.

PhD Justine BILLORE “Thermal aging of XLPE for HVDC cables”
To connect the different points of the network, the transmission and distribution of electric power used cables. Since few years, cables and especially their insulation part are evolving, going from paper insulation to a synthetic insulation. Nowadays, the insulation part of HVDC cables is in crosslinked polyethylene or XLPE.

SimHydro 2017: Choosing the right model in applied hydraulics
This paper focuses on the set up and the validation of a numerical model for the analysis of the flow in reversible Francis pump-turbines in the S-Shape region. For such operating conditions the flow inside the pump-turbine is characterized by highly unsteady flow separations and complex rotor/stator interactions.
