The objective of this project has been the research into the prospective configurations of the ac trolley wire fed traction converter for the new generation of the locomotives and especially suburban units. The presented converter configuration with mediumfrequency transformer is one of the selected promising solutions. The converter consists of indirect frequency converters at its input, medium-frequency transformer and output indirect frequency converter feeding either induction machine or PMSM. The input parts of the indirect converters are composed of voltage-source active rectifiers, which are directly connected to the ac trolley wire. In order to achieve the best dynamic properties of primary active rectifiers, we have proposed the control combining PR controller with predictive model for trolley-wire current control loop. Proposed converter control has been tested on designed prototype of low-voltage single-phase voltage-source active rectifier.
