Laboratory prototype of traction converter with medium-frequency transformer: Master control and diagnostic unit

This contribution deals with the prototype of the main traction converter with medium frequency transformer for AC trolley wire fed locomotives. The attention is paid to the new master control and diagnostic unit. The designed master control unit has been programmed in the LabView development environment. This master unit ensures a human interface between a user and a digital signal processor. In this case, the master unit makes possible both control and diagnostic operations of the laboratory prototype of the traction converter. The master unit was tested by experiments performed on designed traction converter prototype of rated power of 12kW.
