IEC 60146-1-1:20 09规定了使用可控和/或不可控电子阀装置的所有半导体功率转换器和半导体功率开关的性能要求。其主要目的是规定一般变换器的基本要求以及适用于交流电转换的线路换向变换器的要求。向华盛顿供电。权力，反之亦然。本标准的部分内容也适用于其他类型的电子功率转换器，前提是它们没有自己的产品标准。第四版是一次技术修订，引入了五个主要变化: -根据现行指令重新编辑整个标准； -更正定义并增加新术语，特别是有关EMC、谐波失真和绝缘的术语-圣职； -根据IEC 61000系列修订了使用条件公差； -考虑到绝缘配合，已修订绝缘测试； -增加三个附件。

IEC 60146-1-1:2009 specifies the requirements for the performance of all semiconductor power converters and semiconductor power switches using controllable and/or non-controllable electronic valve devices. It is primarily intended to specify the basic requirements for converters in general and the requirements applicable to line commutated converters for conversion of a.c. power to d.c. power or vice versa. Parts of this standard are also applicable to other types of electronic power converter provided that they do not have their own product standards. This fourth edition constitutes a technical revision and introduces five main changes:
- re-edition of the whole standard according to the current directives;
- correction of definitions and addition of new terms, especially terms concerning EMC, harmonic distortion and insulation co-ordination;
- the service condition tolerances have been revised according to the IEC 61000 series;
- the insulation tests have been revised considering the insulation co-ordination;
- addition of three annexes.
