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...

Integrating eco-design methods for circular Power Electronics Converters (PECs) based products in industry is crucial to endorse Sustainable Development Goals within planetary limits. However, eco-designing Power Electronics (PE) remains today on optimising the energy efficiency and the power density of the usage phase of the electronic designed. P...
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...
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...
