摘要：The structure of half-wavelength transmission lines makes its transmission characteristics very unique. Therefore, this paper investigated the half-wavelength transmission lines' harmonic transmission characteristics. Firstly, a simulation model for the half-wavelength lines was established and two typical working conditions were analyzed based on the Frequency Dependent (Phase) Model. Secondly, the harmonic transfer coefficient of short-distance lines was compared to that of the half-wavelength lines. Finally, a harmonic source was put into the half-wavelength transmission system and the voltage distortion rate was compared. The results show that the harmonic transfer coefficients of the half-wavelength lines are different from that of short-distance lines. The voltage distortion rate at the start and the end of the lines shows linear variation with the increase of harmonic number, and the distortion rate shows fluctuation when it is at the middle of the lines. The research can provide technical support for the development of half-wavelength transmission technology.
