Your future responsibilities
The master thesis is related to an ongoing research project at SAL, which is dedicated to improving metallurgic processes by applying modern power electronics. The objective is to investigate GaN-transistor based converter stages, which are operated at very high currents (several thousand Amperes in the final configuration). A special focus must be placed on the PCB-layout for achieving minimum loop inductances and optimized cooling as well as on solutions for short circuit protection. The activities will be supported by several experienced colleagues.
The main tasks of the master’s thesis will be:
The main tasks of the master’s thesis will be:
- Perform literature review (focus on paralleling GaN-transistors articles, patents, etc.).
- Simulation-based design of the converter stage (including short circuit protection).
- PCB-design with a focus on minimized loop inductances and optimized cooling.
- Laboratory testing and analysis.
- Perform data analysis and prepare reports.
