Rehabilitation of the tram DC traction with modern power converters

Abstract

This paper approaches problems of tram DC motors traction system modernization, system widely used in the area of Eastern Europe. First, the state-of-the-art and an overview of trams equiped with DC motors and classical rheostatic control system are presented. Poor economic status of this region only allows upgrading these trams with modern power converters. These improve the burning issues and allow reducing energy consumption and raising operational reliability. Second, the paper proposes the rehabilitation of the traction system with an new developped electronic module SDMC-103-04.
