%0 Journal Article %T New Configuration of Traction Converter with Medium-Frequency Transformer: Primary Part %A Vojtech Blahnik %A Zdenek Peroutka %A Jan Molnar %A Jan Michalik %J Advances in Electrical and Electronic Engineering %D 2008 %I Technical University of Ostrava %X This paper deals with new configuration of the traction converter with medium-frequency transformer intended for ac trolley wire fed locomotives. It is concerned to the primary serially connected single-phase voltage-source active rectifiers, which are directly connected to the trolley wire. This contribution presents the proposed control of the primary active rectifiers, simulation and experimental results of designed low-voltage laboratory prototype of converter of rated power of 12kW. %K Traction konverter %K PWM %K medium-frequency transformer. %U http://advances.utc.sk/index.php/AEEE/article/view/56
