摘　　要：针对某型动车组牵引变压器滤波绕组的滤波效果展开研究,结合动车组主电路结构及载波移相控制策略对其网侧谐波进行理论分析、仿真对比、实车试验验证。结果表明,既有动车组动力单元较多时,网侧牵引绕组数量也相应增多,可以通过载波移相技术有效的将高频谐波移至更高频处,而不需要额外增加滤波电路进行高次谐波的滤波。In this paper,the effect of the traction transformer＇s filtering winding was analyzed.Theoretical analysis,simulation comparison and actual vehicle test were done to analyze the harmonic combined with the EMU＇s main circuit structure and carrier phase shift control strategy.The result shows that the high frequency harmonics can be moved to a higher frequency if the EMU has a large number of traction units.As there is a large number of traction winding,the RC circuit will be unnecessary in the EMU.
