چکیده
Active Power Filter (APF) can significantly compensate the current harmonics produced by nonlinear loads. To do this feature, harmonic detection reference generation play vital role. Direct Controller (DPC) has great harmony with instantaneous power compensation (PQ) algorithm as well ability to eliminate internal loops. In addition, DeadBeat (DBC) high compatibility for digital implementation, superior control performance and fast dynamic response. However, DBC suffers from time delay linked action calculation implementation. paper, a new deadbeat-based DPC method is proposed firstly generate of APF. Secondly, simple robust aforementioned deadbeat thanks online/offline predictions. Several simulations are conducted in MATLAB/SIMULINK verified experimental tests obtained DSP-based active filter illustrate effectiveness method. By employing method, Total Harmonic Distortion (THD) grid decreased 22% 3% under steady state condition. While response validates significant transient improvement.
