After establishing two successful Power Semiconductor and Module Reliability Working Groups for automotive and for the railway application, ECPE initiated this discussion within the Renewable Energies community. An ECPE Expert Discussion on ´Power Electronics Reliability in Renewable Energy Applications´ has been organized in Feb. 2022 discussing and prioritizing topics of interest and follow-up action. In the next step an ECPE Workshop on ´Power Electronics Reliability in Outdoor Grid-Connected Systems´ was held in June 2022 in Berlin. As a conclusion it has been agreed to organize further Expert Discussions on specific topics. These online events will start in autumn 2022 with the multi-stressor topic and multimodal testing as well as with the HV-H3TRB test with agreed parameters for the renewable energy/outdoor application.
