IEC 62590-1:2025 specifies the common requirements and definitions for all power converter applications in fixed installations for power supply of railway systems.

This document applies to fixed installations of following electric traction systems:

railway networks,

metropolitan transport networks including metros, tramways, trolleybuses and fully automated transport systems, magnetic levitated transport systems, electric road systems.

This document applies to AC/ DC converters, DC converters and AC converters. Converters for improvement of power quality and for energy saving are also included.

Converters connected to electric traction systems feeding 3AC, 1AC or DC systems for auxiliary purpose are not in the scope of this document but some aspects such as insulation coordination and railway specific conditions can be referred to.

This document, in conjunction with the other parts of IEC 62590, cancels and replaces IEC 62589:2010 and the former IEC 62590:2019.

This document includes the following significant technical changes with respect to IEC 62589:2010 and the former IEC 62590:2019:

a) Split into common requirements and special requirements for different converters

b) Interface Model for the different systems connected

c) Split into circuits with their requirements like insulation coordination

d) Energy efficiency addressed.
