High-Power Electronics and System Engineering

In the "High Power Electronics and System Engineering" topic, we research, develop, test and characterize new technological approaches such as the use of SiC power semiconductors in power converters for low and medium voltage up to the multi-megawatt range. Our constant aim is to optimize the overall system in order to reduce costs and material resources, for example.

In achieving the expansion targets for energy generation from renewable energies, large-scale PV power plants in the megawatt range and the integration of considerable storage capacities are required in parallel with small decentralized systems. In addition to traditional grid feed-in, hybrid power plant solutions (e.g. PV storage power plants) and industrial prosumer concepts are becoming increasingly important.

We are specialized in the development of new system approaches and technologies using power electronics for medium voltage as well as power converters for PV battery systems, hybrid power plants and high-performance charging hubs for a sustainable energy, mobility and heat transition.

Our extensive, high-tech laboratory infrastructure with test and development facilities for DC and AC systems in the voltage range up to 40 kV and outputs up to 20 MVA forms the basis for our services on behalf of our industrial partners and public clients.
