Master’s Thesis: Evaluation of Soft-Switching Topologies for High-Efficiency Power Electronics

Bygg, teknik och hantverk · Bygg- och industriteknik · Maskinteknik

I korthet

This Master's thesis, part of the Horizon Europe Moore4Power project, focuses on evaluating soft-switching topologies for high-efficiency three-phase inverters using SiC and GaN semiconductors. The research involves modeling, simulation, and comparison against hard-switched references to assess efficiency gains, loss reduction, and control complexity.

Ansvarsområden

Review literature on soft-switching principles and three-phase inverter topologies.
Define common inverter specifications.
Build a hard-switched reference model.
Design and dimension selected soft-switching topologies (resonant components, auxiliary switches, device selection, commutation timing).
Build simulation models in PLECS, Matlab/Simulink, and/or SPICE.
Map losses and efficiency across operating points, breaking down losses into conduction, switching, auxiliary-circuit, and passive-component losses.
Evaluate trade-offs: efficiency, THD, component count, device stress, modularity, and scalability.
Explore load-adaptive soft-switching control or hybrid switching strategies (if time allows).
Document work in a thesis report and oral presentation.

Krav

Final year of an MSc program in Electrical Engineering, Electric Power Engineering, Mechatronics, or similar.
Solid knowledge of power electronics.
Experience with circuit simulation (PLECS, LTspice/PSpice, or MATLAB/Simulink).
Good written and spoken English.

Önskade kvalifikationer

Analytical mindset.
Independence.
Good communication skills.

Förmåner

30 ECTS credits (full time).
Start January 2027.
Access to simulation tools licenses.
Supervision by RISE.
Compensation according to RISE’s Guidelines for thesis projects.

Om RISE Research Institutes of Sweden

As the challenges facing us as a society become increasingly complex, innovation alone is not enough; you need a strong innovation partner who can provide comprehensive support and a broad range of perspectives. This is where RISE comes in. RISE is a unique mobilisation of resources to increase the pace of innovation in our society. By gathering a number of research institutes and over a hundred test beds and demonstration environments under the umbrella of a single innovation partner, we create improved conditions for society’s problem solvers. We gather around challenges and organise…
