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 characteristics of the digital band-pass filter are analyzed. The difference between the analog band-pass filter and the digital filter is compared. A harmonic detection method based on the band-pass filter is proposed, which is simple and effective. The parallel active power filter based on this method is constructed. Simulink is used to simulate this active power filter system. The filter system is implemented in the experimental device with TMS320LF2407 as the control core. Simulation and experimental results prove the feasibility of this method.
