Closed‐loop input current control strategy based on waveform similarity index for the emerging matrix converters with harmonic injection technique

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
This paper introduces the waveform similarity index (WSI), which is an effective index to characterise the input current performance of harmonic injection matrix converter (HIMC). A closed‐loop control strategy is proposed to regulate the WSI difference through multi resonant controllers (RCs), which can fully suppress the effect of inaccurate harmonic
