Master's Thesis: Combined Thermal and Loss Modeling of High-Performance Semiconductors

About the role

This Master's thesis at ABB Corporate Research focuses on developing coupled thermal and loss models for semiconductor devices used in DC circuit breakers. The work supports the design of more efficient and reliable DC protection systems.

Key responsibilities

• Review existing thermal and loss models for Si IGBTs and SiC MOSFETs.
• Investigate temperature dependencies of electrical and thermal characteristics.
• Develop multi‑physics COMSOL simulations at the packaging level.
• Design and execute laboratory experiments to validate simulation results.
• Document methodologies, findings, and conclusions in a detailed report, with potential for publication.

Required profile

• Enrolled in a Master’s program in Electrical Engineering, Mechanical Engineering, Physics or a related field.
• Analytical, structured mindset with curiosity for both theory and hands‑on lab work.

Required skills

• Experience with COMSOL (finite element) simulation.
• Familiarity with circuit simulation tools such as PLECS or Simulink.
• Basic knowledge of semiconductor devices (Si IGBTs, SiC MOSFETs).
