Mitrac traction and auxiliary converters: Unprecedented range of service-proven solutions

Mitrac Power and Supply at a glance
Alstom draws on its 50-year experience in designing and manufacturing Mitrac™ propulsion systems and components for all types of rolling stock, weather for new-build or refurbishment applications. Mitrac Power™ traction converters and Mitrac Supply™ auxiliary converters are designed to fit the most challenging climatic conditions, while ensuring outstanding reliability, availability and performance.
Rolling stock owners can count on Alstom’s permanent Research & Development capabilities, supported by long-standing experience and feedback from the ground. Relying on the most up-to-date semi-conductor innovations, we provide our customers with the latest proven technology to power both Alstom and non-Alstom trains.
Owners choose our Mitrac propulsion solutions safe in the knowledge that they have a flexible, knowledgeable and experienced partner with a proven track record in rolling stock and propulsion technology. Complying with the latest safety standards, our Mitrac propulsion components offer high reliability, efficiency and maintainability for worry-free and cost-effective operations.
Our technologies and solutions are based on eco-design principles: low noise, high energy efficiency (including regenerative braking, natural cooling), high recyclability and reduced lifecycle costs. As a result of continuous efforts to limit the environmental impact of its products, we have developed low-carbon alternatives to conventional traction systems, for operation on non-electrified lines, such as hydrogen fuel-cell-based traction systems and energy-storage-based traction systems.
Our traction systems are available for all types of rail vehicles, including those not manufactured by Alstom, ranging from locomotives and light-rail up to regional and high-speed train. They are specifically designed for all types of traction and operating conditions. Our Mitrac traction solutions are guaranteed to meet a wide range of requirements for various voltage levels, extreme temperatures or humidity levels, or when fitting into specific spaces on vehicles to achieve higher passenger capacity.
