IEC 62590:2019作为IEC 62590:2019 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62590:2019规定了所有固定装置电子功率转换器的性能要求，使用可控和/或不可控电子阀，用于牵引电源。这些装置可以通过电流、电压或光来控制。假设非双稳态器件在开关模式下工作。 本文件适用于下列电力牵引系统的固定装置: -铁路， -引导大众运输系统，例如:有轨电车、轻轨系统、高架和地下铁路、山区铁路、无轨电车。 本标准基于EN 50328。第二版取消并取代了2010年出版的第一版。与上一版相比，此版本包括以下重大技术变更: a)结合DC转换器。 b）纠正前一版本中由于PD错误使用而导致的间隙和耐压。 c)结构调整、词汇调整、删除未使用的术语和缩略语。

IEC 62590:2019 is available as IEC 62590:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62590:2019 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 document applies to fixed installations of the following electric traction systems:
- railways,
- guided mass transport systems such as: tramways, light rail systems, elevated and underground railways, mountain railways, trolleybuses.
This standard is based on EN 50328. This second edition cancels and replaces the first edition published in 2010. This edition includes the following significant technical changes with respect to the previous edition:
a) Incorporation of DC converters.
b) Correction of the clearances and withstand voltages due to erroneous use of PD in former edition.
c) adaption of structure, adaption of vocabulary, removal of unused term and abbreviations.
