New configuration of traction converter with medium-frequency transformer: primary part

摘要

This paper deals with new configuration of the traction converter with medium-frequency transformer intendedfor ac trolley wire fed locomotives. It is concerned to the primary serially connected single-phase voltage-source activerectifiers, which are directly connected to the trolley wire. This contribution presents the proposed control of the primaryactive rectifiers, simulation and experimental results of designed low-voltage laboratory prototype of converter of ratedpower of 12kW.
