Staffan Norrga was born in Lidingö, Sweden, in 1968. He received the M.Sc. degree in applied physics from Linköping Institute of Technology, Linköping, Sweden, in 1993 and the Ph.D. degree in electrical engineering from the Royal Institute of Technology (KTH), Stockholm, Sweden, in 2005. Between 1994 and 2011, he worked as a Development Engineer at ABB in Västerås, Sweden, in various power-electronics-related areas such as railway traction systems and converters for HVDC power transmission systems. In 2000, he returned to academia to engage in research on new power electronic converters employing soft switching and medium frequency transformers, at the Department of Electric Machines and Power Electronics of the Royal Institute of Technology. He currently holds a position as Associate Professor at the same institution. His research interests include new converter topologies for power transmission applications and grid integration of renewable energy sources. He is the inventor or co-inventor of 11 granted patents and 14 patents pending and has authored or co-authored more than 75 scientific papers published at international conferences or in journals.
