Strong alliance aimed at reducing LCOE

Power electronics have developed into a key technology of the 21st century. For example, power electronic components serve to control renewable energy systems and allow optimal exploitation of the different renewable energy sources and feeding in of the generated power into the public grid in consistent with grid codes. This project focuses on main converters in wind turbines, which are decisive for compliance with the stringent quality requirements for energy to be fed into the grid. These converters regularly incur damage which results in relevant repair costs and downtimes and thus raise the energy generating costs of a wind plant unnecessarily.

The Fraunhofer Innovation Cluster “Power Electronics for Renewable Energy Supplies” has two lead projects:



“Reliable power electronics for wind plants”

Lower Saxony lead project, coordinated by: Fraunhofer IWES


“New converter concepts for feeding electrical energy into the grid up to 1,700 V, 1,000 A”

Schleswig-Holstein lead project, coordinated by: Fraunhofer ISIT
