TLDR
In this article, the authors proposed an analysis technique that can be used to calculate the transferred harmonics using amplitude modulation (AM) theory in a high-voltage direct-current (HVDC) link.Abstract:
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. >read more

TL;DR: In this paper, the most remarkable issues related to interharmonic theory and modeling are presented, starting from the basic definitions and concepts, attention is first devoted to inter-harmonic sources, and then the interharmonics assessment is considered with particular attention to the problem of the frequency resolution and of the computational burden associated with the analysis of periodic steady-state waveforms.

A Harmonically Coupled Admittance Matrix Model for AC/DC Converters
TL;DR: In this article, the authors proposed a new method to model the harmonic generating characteristics of AC/DC converters, which transforms the time domain nonlinear characteristic of the converter into a frequency domain linear admittance matrix, which represents the coupling among the converter AC side harmonic voltages and currents accurately and does not vary with the harmonic conditions of the system.
