Inverters in photovoltaic systems and wind turbines are indispensable technological components of the energy transition. However, due to the combination of climatic, thermal and electrical loads, they are among the most frequently failing system components. In the recently completed project "Reliable converters for renewable energy supply (power4re)", five institutes of the Fraunhofer-Gesellschaft, including the Fraunhofer Institute for Microstructure of Materials and Systems IMWS, have developed significantly improved solutions. They have gained new insights into weak points, damage patterns, influencing factors and failure mechanisms and developed improved test methods to increase robustness and reliability.
