IEC 62590-2-2:2026 pdf download,Railway applications – Electronic power converters for fixed installations – Part 2-2: DC Traction applications – Controlled converters.
IEC 62590-2-2:2026 defines functions, operating principles, requirements, interfaces, and test methods for controlled converters used in DC traction fixed installations. It is part of the IEC 62590 series for electronic power converters in railway electrification, building on general requirements in IEC 62590-1 and relating to other parts for uncontrolled rectifiers and other traction converter categories.
The standard covers AC/DC converters such as controlled rectifiers, inverters, and combinations, as well as DC converters. A key purpose is to enable the converters to influence power flow in the DC traction system, supporting bidirectional or controllable energy transfer, including links to other power networks and energy storage. It addresses converter operating modes where power can be directed with control, including types that may be line-commutated or self-commutated.
Its scope applies not only to conventional railway networks, but also to metropolitan transport (metros, tramways, trolleybuses, automated transport systems), maglev, and electric road systems. The document specifies verification activities including protection behavior, insulation and safety-related checks, performance measurements such as loss determination, tests for electromagnetic compatibility, and mechanical integrity assurance. Overall, it standardizes how controlled DC traction converters are specified and validated so they meet safety, reliability, and interoperability needs in demanding traction environments.
