摘要：

The existing modulation methods of matrix converter (MC) are difficult to consider both output harmonic and common-mode characteristics, and the influence of modulation parameters on output characteristics is not quantified. Based on the principle of triple Fourier transform, this paper established the mathematical equations among modulation parameter two zero-voltage vector action time, voltage transfer ratio (VTR), output voltage common-mode components and harmonic components, and then quantitatively analyzed the effect of two zero-voltage vector action time on common-mode component and harmonic component, which provided a theoretical basis for the modulation method considering the zero vector action time on the output characteristics. Based on the analysis of the two zero-voltage vector action time on the output characteristics of IMC, the optimal two zero-voltage vector action time was obtained under different VTR, thereby greatly reducing the output low-frequency common-mode component amplitude to effectively suppress the leakage current and further improve the IMC output performance. Finally, the correctness of the theoretical analysis in this paper was verified by experiments. ©2022 Chin.Soc.for Elec.Eng.
