摘　　要：提出了一种利用晶闸管控制电抗器为可变电抗器的新型可控无源滤波器。通过改变触发角来改变可变电抗器的等效电感,使滤波器在LC参数变化后重新回到谐振状态以实现自动调谐。实验证明该滤波器适于一般电力电子装置的谐波抑制。This paper presents a novel controllable passive filter which uses the thyristor controlled reactor (TCR) as a variable reactor. The equivalent inductance of the variable reactor changes by adjusting the thyristor's triggering angle to make the filter resonant after the LC parameters are varied. The theoretical analysis and experiment of this filter are given, the results show that the proposed passive filter is suitable for harmonics mitigation for most of power electronic equipments.
