摘　　要：以传统双T型无源带阻滤波器为基础并加入反馈电路设计了Q值可调的50Hz陷波电路。仿真实验表明该电路Q值连续可调且具有良好的选频特性,能最大程度地抑制50Hz工频干扰。Based on the traditional no source band-stop filter named double T and use feedback circuits ,a 50Hz frequency trap filter whose Q values are adjustable is designed .The simulation experiment indicates that the circuit can adjust the Q values continuously ,and it has good characteristics to choose the frequency, it can suppress the power interference of 50 Hz greatly.

关 键 词：陷波器 工频干扰 选频特性
