Abstract: We present technical specifications and experimental results of test running of a railway vehicle equipped with fuel cells in this paper. We are currently under development of railway vehicle equipped with fuel cells. We made a trial product of a railway vehicle equipped with 100-kW class fuel cells, and carried out experimental running tests. This paper has focused on the following features: a. Specifications for the test railway vehicle equipped with fuel cells: Fuel cells, hydrogen storage cylinders, motors, and inverter b. Outline of the test railway vehicle, equipment layout and configuration of traction circuit c. Experimental test results on a test track Motor characteristic of the test railway vehicle, train performance curve and test results d. Experimental test results at a rolling stock test facility Motor characteristic of the test vehicle and test results e. Evaluation of electrical output characteristics of fuel cells Through our research as described in the paper, we anticipate to promote an-environment-friendly railway system.

Abstract: Advanced multi-system propulsion technology for passenger trains and locomotives' cross-border operation all over Europe is integrating latest IGBT semiconductors and control technology into traction and auxiliary supply. Reliability as well as operating and maintenance cost have been in the focus of system concept and product design. All high voltage circuits, power electronics and control units are integrated to a higher degree than with conventional existing arrangements, which results in unmatched power densities for the MITRAC traction and auxiliary power supply system. A lifecycle cost (LCC) oriented system design with fully controlled DC link voltage enables operation with minimal energy consumption. Moreover, the high degree of functional integration as well as the maintenance cost optimized design are contributing to lower manufacturing and maintenance costs, higher reliability, and reduced total space and weight. Current applications as the TRAXX MS locomotives Re484 (SBB) and E186 (ATC, CBRail) as well as the large number of delivered trains of the AGC family illustrate the successful application of these most advanced propulsion systems.

Abstract: The proposed Medium Frequency Topology is replacing the bulky main line transformer on board of railway vehicles. Especially in countries with 15kV railway power supply, the low frequency of 16.7 Hz is leading to huge and heavy transformers. Today's Transformers are often minimized in weight and volume, which leads to significantly high transformer losses compared with distribution transformers. The Medium Frequency Topology is the power electronic solution that considerably reduces weight and losses of the traction system.
