在变流器机车上使用有源网侧滤波器可以大大减少变流器产生的电网电流谐波含量。与无源滤波器不同,此时在网压畸变时也没有附加无用电流。使用有源滤波器可使机车优化,并使机车产生的功率损耗少于不用或用无源滤波器机车的。
The use of active-side filter on the converter locomotive can greatly reduce the current harmonic content of the grid current generated by the converter. Unlike passive filters, there is no additional useless current during network voltage distortion. The use of active filters optimizes the locomotive and gives the locomotive less power than it does or does not use passive filters.
