Introduction
Semiconductor converters for traction power supply differ from other converters for industrial
use due to special electrical service conditions and due to the large range of load variation and
the peculiar characteristics of the load.
For these reasons EN 60146-1-1 does not fully cover the requirements of railway applications
and the decision was taken to have a specific European standard for this use.
Converter transformers for fixed installations of railway applications are covered by EN 50329.
Harmonization of the rated values and tests of the whole converter group are covered by
EN 50327.
1 General
1.1 Scope
This European Standard specifies the requirements for the performance of all fixed installations
electronic power converters, using controllable and/or non-controllable electronic valves,
intended for traction power supply.
The devices can be controlled by means of current, voltage or light. Non-bistable devices are
assumed to be operated in the switched mode.
This European Standard applies to fixed installations of following electric traction systems:
− railways,
− guided mass transport systems such as: tramways, light rail systems, elevated and
underground railways, mountain railways, trolleybusses.
This European Standard does not apply to
− cranes, transportable platforms and similar transportation equipment on rails,
− suspended cable cars,
− funicular railways.
This European Standard applies to diode rectifiers, controlled rectifiers, inverters and frequency
converters.
The equipment covered in this European Standard is the converter itself.
