Railway applications - Electronic power converters for fixed installations - Part 2-2: DC applications - Controlled converters

Scope

IEC 62590-2-2: 2026 describes functions and working principles, specifies requirements, interfaces, and test methods for controlled converters for DC electric traction power supply systems:

– AC/DC converters:

• rectifiers,

• inverters,

• combinations.

– DC converters.

The purpose of the converters can be a power connection to other power networks or energy storages.

The common characteristic of this equipment is the possibility to influence the power flow in the DC electric traction power supply system. The converters can be:

– line-commutated;

– self-commutated.

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

– railway networks,

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