Internship "Design, implementation and evaluation of double-pulse tests for WBG power modules"

The Fraunhofer Institute for Solar Energy Systems ISE in Freiburg is the largest solar research institute in Europe. Our around 1400 employees work for a sustainable economical safe and socially fair energy supply system based on renewable energies. We contribute to this with our research priorities of energy supply energy distribution energy storage and energy use. Through outstanding research results successful industrial projects spin-off companies and global cooperation we shape the sustainable transformation of the energy system.

For our group Power Converters we are looking for a motivated student to join us as soon as possible for a voluntary internship or a mandatory internship in the field Design implementation and evaluation of double-pulse tests for the characterization of wide-bandgap power modules

The use of wide-bandgap power semiconductors made of silicon carbide (SiC) and gallium nitride (GaN) promises many advantages over semiconductors made of silicon including reduced switching losses higher switching frequency and improved power density. Power modules with GaN or SiC power semiconductors require new module concepts with adapted assembly and interconnection technology to exploit the full potential of the semiconductors. The switching behavior of new types of power modules is to be characterized by double-pulse tests. For this purpose individual measurement setups must be designed and constructed for the test specimens. GaN and SiC power semiconductors are particularly demanding in terms of measurement setups and methods. Various measurement methods are to be compared in a preliminary study. After carrying out the double-pulse tests the measurement results are to be evaluated using Python to compare the different wide-bandgap power modules.

Was Du bei uns tust

• Your tasks include the investigation of various measurement methods.
• You create circuit diagrams and PCB layouts in Altium Designer to enable double-pulse tests on new types of power modules.
• You assemble the designed PCBs with the components.
• You carry out double-pulse tests to characterize the switching behavior of new types of power modules.
• You evaluate the measurement results using Python.
• You compare and evaluate different power modules.
• You create a final documentation.
