摘　　要：分析了数字带通滤波器的特点,比较了模拟带通滤波器和数字滤波器的区别,提出了一种基于带通滤波器的谐波检测方法,这种方法简单有效。构造了基于这种方法的并联型有源滤波器,对这种有源滤波器系统用Simulink进行仿真,并在以TMS320LF2407为控制核心的实验装置中对这种滤波器系统作了具体的实现。仿真和实验结果证明了这种方法的可行性。The characteristic of digital band pass filter is analyzed, the difference between it and analog band pass filter is compared, a harmonic detection algorithm based on it is given. This algorithm is very simple and effective. In addition, a shunt active filter using this algorithm is constructed, The simulation result based on Simulink and experiment result based on TMS320LF2407 are given. The results show the algorithm is valid and effective.
