New Configuration of Traction Converter with Medium-Frequency Transformer: Primary Part

Abstract

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.
