Overview
IEC 62590:2010 is an international standard published by the International Electrotechnical Commission (IEC) that specifies performance requirements for electronic power converters installed in fixed railway substations. These electronic power converters utilize controllable and/or non-controllable electronic valves designed primarily for traction power supply systems. The standard addresses converters controlled through current, voltage, or light signals and assumes non-bistable devices operate in switched mode. IEC 62590:2010 ensures consistent performance, safety, and interoperability across railway traction power installations globally.
