IEC 62747:2014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）的应用情况编写，但也可用于指导使用其他类型的半导体器件的情况，这些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）输电系统的线路换流和电流源换流器不在本标准范围内。

IEC 62747:2014 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.
