| 摘 要： | 悬浮斩波器是EMS型磁浮列车上的开关型电流放大器,由此造成输入电源的电流纹波较大。对双正激斩波器和三电平悬浮斩波器的输入电流波动方程进行了推导,对比发现,在相同输出电流条件下,三电平悬浮斩波器的输入电流波动更小。基于PspiceAD平台建立了悬浮斩波器模型,仿真研究验证了分析结论。最后,对自主研制的悬浮斩波器样机进行了实验对比测试。

| Abstract: | Maglev chopper is the switch mode current amplifier on EMS maglev train,and the input current ripple is significant.The variation relationship of input current of two-level and three-level double forward chopper were derived respectively.The input current ripple of three-level maglev chopper is much less than the two-level one.Furthermore,the model of maglev chopper is constructed on the Pspice AD platform,and is used for simulation.Finally,the novel maglev chopper is evaluated by experiments. |
