We are experts in testing power converters for photovoltaic and battery applications, combined heat and power plants (CHP) and DC fast charging stationsfor electromobility in the multi-megawatt range. Typical measurement campaigns concern grid connection guidelines, efficiency, temperature-dependent derating as well as customer-specific tests and benchmarks.
Our future power grid will experience a significant increase in power electronics. With the research and development activities in our lab, we contribute to ensuring grid stability. In TestLab Power Electronics, we measure PV inverters, battery converters, rectifiers, combined heat and power plants, DC/DC converters, DC fast charging stations as well as power electronics for fuel cells and electrolysers from a few watts up to the multi-megawatt range.
We perform accredited measurements according to various grid connection guidelines, for example FGW TR3, and measure efficiencies according to EN 50530, among others. As part of our research activities, we have derived accredited procedures, for example for determining the efficiency of bidirectional converters or our innovative differential impedance spectroscopy. In addition, we support our customers in individual issues, for example troubleshooting in the laboratory or in the field, in measurement of temperature-dependent derating of power or in quality-assuring measurements before product launch.
Nowadays, detailed simulations of power electronic components are indispensable for system development. We offer services and assistance in the field of simulation and modeling of individual generation units such as PV inverters or CHPs, but also, for example, of complete PV power plants.
We measure a wide variety of power electronic components in our laboratory, especially inverters for photovoltaic and battery systems. The most frequent measurement campaigns in the field of photovoltaics are carried out on string inverters with up to 350 kVA power and for central inverters with up to approx. 5 MVA power. In the field of battery systems, inverters with outputs ranging from a few kilowatts to the megawatt range are measured. Likewise, DC fast charging stations are being measured more and more frequently; these now also reach power classes of up to 400 kVA (CCS) and will also offer charging power in the megawatt range (MCS) in the future.
Our multi-megawatt class infrastructure also enables us to offer measurements of power electronics for large-scale systems, such as combined heat and power plants, electrolysers, heat pumps and other generators and consumers. In the near future, these devices will also have to meet specific requirements under the grid connection guidelines / grid codes. We are prepared for these foreseeable measurements and are happy to support our customers individually in preparing for these upcoming developments. Measurements can be carried out in our laboratories or outdoors, as well as in the field.
