Siemens to install state-of-the-art IGBT tech for IR
Given its position as a trusted partner of the Indian Railways for the last six decades, Siemens will be designing, supplying and installing AC Traction systems for Dual Cab High Horsepower Diesel Engine locomotive for Diesel Locomotive Works (DLW) for the IR, with a focus on modernisation, expansion of rail networks and energy efficiency.
The systems have been developed based on the Insulated Gate Bipolar Transistors (IGBT) technology; with the AC Traction systems to be produced at Siemens Limited’s Nashik factory. 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, minimising heat and traction noise while also making the acceleration process efficient. Tilak Raj Seth, Executive Vice-President and Head, Mobility, Siemens Limited said, “The advent of IGBTs has yielded strong efficiency gains in electric drive technology. The project showcases Siemens’ partnership with the Indian Railways as it combines innovation with responsibility to bring together the combined expertise of its teams, that is committed to deliver reliable, safe and efficient technologies.”
