Short Biography

Sönke Rogalla graduated from Karlsruhe Institute of Technology (KIT), Karlsruhe, Germany in 2006 with the degree of Diplom-Ingenieur in Electrical Engineering and Information Technology with a specialization on Renewable Energies. In 2015, he spent time as a visiting scientist at the Rensselaer Polytechnic Institute (RPI) in Troy, New York, researching the topic of grid stability with converters. He received his Ph.D. degree in Electrical Engineering from the University of Braunschweig - Institute of Technology, Germany, in 2020 on "Grid Interaction of Converters and Impedance Spectroscopy of Inverters".

Since 2006, he is with Fraunhofer Institute for Solar Energy Systems ISE, Freiburg Germany. He was responsible for different research groups in the fields of PV inverter development, high power electronics, inverter testing, PV system concepts, grid interaction of converts and grid-forming converts. Soenke Rogalla was in charge of planning and setting up Fraunhofer ISE's Multi-Megawatt Laboratory. Since 2022 he is the co-head of the department "Power Electronics and Grid Integration".
