摘　　要：针对当前谐波过滤方法存在的问题,提出了一种基于相间耦合的新型无源滤波方法,即通过在正弦交流电源与负载间串联具有电磁耦合的电抗器来进行谐波过滤。实验结果表明:该方法不需要复杂的控制就可对谐波电流具有较好的抑制性能,结构简单、经济可靠,可适用于大功率场合应用。In allusion to existing problems in present harmonic filtering method,a new type passive filtering method based on interphase coupling was raised.In other words,electromagnetic coupling reactors were connected in series between sine AC current power and load to carry out harmonic filtering.The experiment shows that the method can have better control restriction performance for harmonic currents without complicated control.The structure is simple,economic and reliable,adoptable to be used for large power site.
