IEC 62590-2-1 Ed. 1.0 b:2025

Railway applications - Electronic power converters for fixed installations - Part 2-1: DC traction applications - Uncontrolled rectifiers

IEC 62590-2-1:2025 This document includes the following significant technical changes with respect to IEC 62589 and the former IEC 62590:

a) Reduction of the requirements for uncontrolled rectifiers only;
b) Interface model for the different systems connected;
c) Energy efficiency addressed.

This part of IEC 62590 describes functions and working principles, specifies requirements, interfaces and test methods of uncontrolled rectifiers for DC electric traction power supply systems. Uncontrolled rectifiers connect a 3AC power network with a DC electric traction system with a unidirectional power flow using diode assemblies.

The coordination between the transformer and the rectifier diode assembly is included.

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

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

This first edition of IEC 62590-2-1, in conjunction with the other parts of the IEC 62590 series, cancels and replaces the first edition of IEC 62589 published in 2010 and the second edition of IEC 62590 published in 2019.
