本国际标准定义了用于高压直流输电（HVDC）的自换向电压源变流器的术语。 本标准主要针对电压源转换器（VSC）中绝缘栅双极晶体管（IGBT）的应用，但也可用于指导其他类型的 所使用的半导体器件既可以通过控制动作打开，也可以通过控制动作关闭。 高压直流（HVDC）电源用线路换流和电流源换流器 本标准明确排除了传输系统。交叉引用:IEC 60633IEC 60617EN 60633EN 62751-1IEC 62501EN 60146-1-1EN 62751-2IEC 60633EN 60146-2IEC 62751-2IEC 60146-1-1EN 62501EN 60747IEC 60146-2IEC 62751-1IEC 60747包含以下内容:修订，2019年5月；勘误表，2015年3月

This International Standard defines terms for the subject of self-commutated voltage-sourced converters used for transmission of power by high voltage direct current (HVDC). The standard is written mainly for the case of application of insulated gate bipolar transistors (IGBTs) in voltage sourced converters (VSC) but may also be used for guidance in the event that other types of semiconductor devices which can both be turned on and turned off by control action are used. Line-commutated and current-sourced converters for high-voltage direct current (HVDC) power transmission systems are specifically excluded from this standard.Cross References:IEC 60633IEC 60617EN 60633EN 62751-1IEC 62501EN 60146-1-1EN 62751-2IEC 60633EN 60146-2IEC 62751-2IEC 60146-1-1EN 62501EN 60747IEC 60146-2IEC 62751-1IEC 60747Incorporates the following:Amendment, May 2019; Corrigendum, March 2015
