DC microgrids have become increasingly popular in recent years. Although they offer various advantages, certain challenges must be faced.A fully operational bipolar DC microgrid with a nominal voltage of ±380 V has already been in service at the Fraunhofer Institute for Integrated Systems and Device Technology IISB in Erlangen for several years and is continuously expanded. It serves as a platform for various DC grid technologies developed at the IISB, e.g. DC/DC- or AC/DC-converters, safety components and battery storage systems. As a living lab, the platform is open for partners from research and industry.
