DC Microgrids for Commercial or Industrial Buildings


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.
