A New Converter Drive System for a Diesel Electric Locomotive with Asynchronous Traction Motors

After a short explanation of the need to develop a new power transmission system, listing the general demands on the performance of a locomotive, the arrangement of an existing diesel electric locomotive, the DE 2500, is presented. The main components of the system, such as the alternator, converter, traction motors, and the whole control system are described in detail. Consideration is given to the interaction between the different components which had to be taken care of in the design. Good operating experience has shown that the system was well chosen. For the future a uniform drive scheme for different power supplies appears realizable.
