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...
The primary objective of this master's thesis is to examine a new version of a power unit currently utilized in an unmanned aerial vehicle and develop a simulation model of the power unit. The theoretical groundwork needed for developing a model has been presented, describing components used and the function of the different subsystems. The develop...

AD-EYE is an ongoing collection of projects at Kungliga Tekniska H¨ogskolan (KTH) in Sweden, aiming to develop a platform for researchers to test autonomous driving solutions in real-world conditions. The future goal of AD-EYE is to create a smart infrastructure at KTH Campus with autonomous driving vehicles. This iteration of the project covers th...
Designing more circular products is essential to reaching Sustainable Development Goal 12, Responsible Consumption and Production, which is anticipated to be achieved by 2030. To achieve progress toward a circular economy in power electronics, discarded products, modules, or components must be recovered. This requires the implementation of End-of-L...
In the context of a rise in the use of static power converters, the beneficial features of Multilevel Modular Converters (MMCs) have led to their popularization. However, as the number of voltage levels and the number of phases increases, these converters have an increasing number of degrees of freedom to handle. Thus, MMCs represent a challenge fo...
There is a reliability concern for wind turbines (WTs) installed in offshore wind farms, where the harsh environment not only has a potential to lead to more failures, but could also increase the time and cost of intervention. Such unreliability problems can cause downtime and losses, which would be reflected at the cost of energy and affect all in...
L'installation de générateurs d'énergie renouvelable distribués tels que les panneaux photovoltaïques sur les toitures ainsi que les éoliennes en milieu rural ou industriel transforme profondément les réseaux de distribution. Ainsi, les flux de puissance dans les lignes électriques du réseau peuvent être fortement modifiés voire inversés, si bien q...
