EN 50328:2003 - 6 - 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. T
27、he 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 rai
28、l 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, contro
29、lled rectifiers, inverters and frequency converters. The equipment covered in this European Standard is the converter itself. 1.2 Normative references This European Standard incorporates by dated or undated reference provisions from other publications.
