IEC/TR 62544:2011（E）给出了高压直流（HVDC）输电用有源滤波器的一般指南。它描述了有源设备主要用于减少直流或交流系统中谐波的系统。这不包括使用自动重新调谐的组件。报告中描述了可用于有源滤波器的各种类型的电路，以及它们的主要工作特性和典型应用。总体目标是为购买者提供指导，帮助他们完成将有源滤波器指定为HVDC换流器的一部分的任务。本报告中明确排除了无源滤波器。

IEC/TR 62544:2011(E) gives general guidance on the subject of active filters for use in high-voltage direct current (HVDC) power transmission. It describes systems where active devices are used primarily to achieve a reduction in harmonics in the d.c. or a.c. systems. This excludes the use of automatically retuned components. The various types of circuit that can be used for active filters are described in the report, along with their principal operational characteristics and typical applications. The overall aim is to provide guidance for purchasers to assist with the task of specifying active filters as part of HVDC converters. Passive filters are specifically excluded from this report.
