已知功率转换器在其AC侧和DC侧上都是谐波发生器。它们还将现有的谐波从一侧转移到另一侧，并伴随频率的相关变化。分析技术，可以用来计算这些转移谐波使用幅度调制（AM）理论的建议。作者还展示了如何在高压直流（HVDC）链路中，转换器可以相互耦合的AC和DC系统，从而可以作为谐波的传输介质。给出了如何计算这些谐波的例子，并与计算机辅助设计（CAD）模型进行了比较，以检查该方法的准确性。>
Power converters are known to be generators of harmonics on both their AC and DC sides. They also transfer existing harmonics from one side to the other side with an associated change of frequency. Analysis techniques that can be used to calculate these transferred harmonics using amplitude modulation (AM) theory are proposed. The authors also show how, in a high-voltage direct-current (HVDC) link, the converters can intercouple the AC and DC systems and can thus act as a transfer medium for harmonics. Examples that show how to calculate these harmonics are given and comparisons are made with a computer-aided design (CAD) model as a check on the accuracy of the method. >
