<abstract>The use of Insulated Gate Bi-polar Transistor as the switching device in rectifier and inverters for high power applications like electric traction as it is efficient, reliable, has improved power factor and also robust. Combined with the technology of manufacture of 3-φ Squirrel Cage Induction Motors, the modern diesel-electric locomotives are driven by dieselengine driven alternators. These modern diesel locomotives are called the Electro-motive Diesels. In this paper, a new drive system with Permanent Magnet Synchronous Motors (PMSM) as traction motors is being suggested by the authors as PMSM are robust, more efficient, work on near unity power factor, and have a higher torque/Volume ratio.</abstract>
