The FHI Power Electronics Event took place from 8 to 10 June 2021. This time it was a digital event due to the restrictions still in place as a result of the Covid-19 pandemic.

TT&MS consultant André Handgraaf gave a general presentation with the topic: “How to choose the right AC power supply for your application?”. As a developer, you want to test all products with a plug for specifications. Does the product work well in the voltage range of 196V to 256V and higher? Or is your product sold worldwide and do you encounter other voltages and more phase sets? What frequencies do you need; 50Hz, 60Hz, 400Hz and 800Hz or higher? Does the product comply with all local standards? There are many other specifications that apply to the AC grid that your design must meet. There is a wide range of AC power supplies available in the market, but what should you look for when making the right choice?

If you have any questions or comments, please let us know.

We are happy to show you our range of AC power supplies.

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
