摘　　要：本文根据自适应噪声对消器的原理设计出一种性能优良的工频电源干扰自适应陷波器。该陷波器对工频提供400倍的衰减;当工频发生±10Hz变化时,陷波器的性能不变;元件参数的变化对陷波器的特性影响不大,-3dB的带宽为3Hz,,使用效果良好。An interference adaptive trapper for operating frequency power supply, based on the principle of adaptive noise canceller, has been designed. It provides a 400 times attenuation for operating frequency. when the operating frequency changes within ±10Hz, its performance remains unchanged. The change of component parameters has little influence on the characteristics of the trapper. The bandwidth of -3dB is 3Hz, and it can be used very well.
