EV fast charging station design and protection

The isolated dc/dc converter is one of the biggest challenges in the design of electric vehicle fast charging stations. This EKSH funded project in collaboration with two local companies supports the development of the next generation of fast charging stations for electric vehicles with Silicon Carbide (SiC) based power semiconductors, which enable to achieve higher efficiency and higher power density. Within the scope of the project, condition monitoring techniques for capacitors and short circuit detection and interruption methods for power semiconductors will be investigated as enabling technologies for reliable and safe fast charging stations.

  • Our research is focused on the design of high efficient and reliable PWM-based power converter architectures (single-cell, multi-cell, multilevel), their modelling and control to exploit commercial as well as new power semiconductor devices with minimum over design.
    We develop controllers for electric drives and we are particularly skilled in the integration of renewable energy systems into the electric grid.
