Abstract
Solid-State Transformer technology continues to attract interest from researchers in academia and industry, and nowadays is strongly considered for the AI data centres. Despite its promise of power density and high performance, the practical design of these highly modular galvanically isolated power electronics converters presents significant challenges. These arise from the high power and voltage requirements of the design, insulation coordination, high-voltage magnetic components, thermal considerations, and the complexity of controller hardware and control algorithms. High modularity significantly impacts the reliability and availability of the SST and has a substantial influence on its scalability in terms of voltage, current, and power ratings. Redundancy is often incorporated into the design, further complicating the realisation of power stages. The lecture will systematically address various technological aspects of megawatt-level SST design, present commonly used technologies, and share first-hand experiences and solutions developed at the Power Electronics Laboratory at EPFL, as well as some recent works related to data centre applications.
Biography
Drazen Dujic is an Associate Professor and Director of the Power Electronics Laboratory at the Swiss Federal Institute of Technology (EPFL) in Lausanne, Switzerland, where he is engaged in research activities in the broad field of electrical energy generation, conversion, and storage, with a focus on medium voltage high power applications. He received his Dipl. Ing. and MSc degrees from the University of Novi Sad, Serbia, in 2002 and 2005, respectively, and his PhD degree from Liverpool John Moores University, UK, in 2008. From 2009 to 2014, he was with ABB Switzerland and engaged in power electronics-related projects spanning the range from low-power power supplies in the kW range to medium voltage high power converters in the MW range. His main research interests are in the areas of design and control of advanced medium-voltage high-power electronics systems and high-performance drives. He is an IEEE Fellow.
