IGBTs are state-of-the-art power electronics for the traction system of electric and diesel-electric rail vehicles. The main benefit of IGBT is that it reduces the requirement for current, minimizing heat and traction noise while also making the acceleration process efficient. Automations solutions provider Siemens Limited has bagged the contract to install state-of-the-art IGBT technology for Indian Railways. The company will be designing, supplying and installing alternating current (AC) traction systems for dual cab high horsepower diesel engine locomotive for diesel locomotive works (DLW). "The systems have been developed based on the state-of-the-art insulated gate bipolar transistors (IGBT) technology. The AC traction systems will be produced at its factory at Nashik, Maharashtra, India" the company said.
