Abstract

Analysis and CAD of electric vehicle power electronic converters as a source of electromagnetic disturbances W. Zajac" & A. Szelag^ "Department of Electrical Engineering, Cracow University of Technology, 31-155 Cracow, Warszawska St 24, Poland ^Institute of Electrical Machines, Warsaw University of Technology, 00-661 Warsaw, PL Politechniki 1, Poland Abstract The problem of disturbances caused by the converters of an electric traction vehicle is discussed in this paper. As there have been projects to introduce new types of rolling stock in a suburban railway line in Silesia (the south-wes- tern part of Poland), some introductory analyses have been done in order to estimate the electromagnetic disturbances which could be caused by the vehicles' converters. As a type of rolling stock, supplied by a 3 kV DC traction system , a multiple unit with a.c. motors and a voltage inverter have been taken into consideration. Specialized software for the simulation of the power electro
