The main objective of this paper is to study the voltage withstand characterization of Printed Circuit Board (PCB) substrates for the development of three-dimension (3D) power modules. Classical power electronics gel encapsulation is substituted by air encapsulation in order to benefit of dielectric and thermal cooling aspects. Breakdown voltage (B...
This thesis presents a practical topology for achieving highly efficient dual-side wireless power transfer (WPT). Traditional WPT systems with a diode rectifier on the secondary side lack flexibility in load matching, requiring the integration of an additional dc/dc converter at the back end. However, this approach leads to increased power losses a...
The transportation sector is moving towards a green future with a rapidly growing EV market and consequently, the demand for EV chargers is rising too. With the increased interest in 800V batteries and the current presence of 400V and 600V batteries, the voltage range for EV chargers is wide (150V-1000V). In this thesis, a wide-output EV charger ba...
This article proposes a generic and complete electrothermal 4H-SiC physical Mosfet model. Static and transient in hard short-circuit operation behaviors are successfully performed using 2D Comsol TM software. Influence of fixed charges and traps at the 4H-SiC/SiO2 interface has been highlighted, both for static and transient. An additional mobility...

Nowadays the electrification of our society leads to a huge demand for technologies related to power conversion systems. Lateral Gallium Nitride (GaN) transistors made on silicon wafers were shown to be more adapted for high-efficiency power conversion over their silicon counterparts in the mid-voltage range (100 V–1000 V) at a reasonable cost. The...
Le silicium est le matériau le plus utilisé pour la fabrication des composants de puissance, car il présente de bonnes propriétés électriques et un faible coût de fabrication. Néanmoins, pour des puissances élevées nécessaires dans les applications en électronique de puissance, le silicium présente sa limite. Pour cela, les développements s’oriente...
Innovations within power electronics are necessary to enable future electric aircraft and space exploration. In these aerospace applications, power converters must be light-weight, efficient and reliable. Conventional, inductor-based, power electronics tend to be heavy, and have high switch stress making them difficult to implement in these applica...
