| Abstract: | An adaptive harmonic current detecting method based on the adaptive noise canceling technology is presented. The adaptive noise canceling technology is briefly introduced and the detecting circuit is analyzed. The proposed circuit is an ideal second-order notch filter. A simulation model of the proposed detecting system is put forward using MATLAB and the simulation curves are given. The simulation results verify the validity of the adaptive harmonic current detecting method. The advantages of the detecting method are simple detecting circuit, better adaptive ability, faster dynamic response and higher detecting precision and so on. |
