| Abstract: | Line converter of CRH2 EMUs was constituted of single-phase three-level topological structure.Based on the calculation of single-phase two-level converter input harmonic,harmonic characteristic of single-phase three-level converter input voltage & current was analyzed.The factors impacting THD of converter input current were studied,and the input inductance design principle was expounded.Results of simulation with MATLAB and practical test validated the theoretical analysis. |
