Novel Algorithm

A novel algorithm for a single-phase active power filter (APF) is proposed in this paper. The proposed algorithm avoids the use of main voltage signal in the calculation of reference compensation current. Therefore, the mains current after compensation is still a pure sinusoidal waveform even when the mains voltage is distorted. A novel circuit for detecting the amplitude of the real part of the fundamental load current is not more than 1/4 cycle. Its transient response is superior to the other conventional techniques. In addition, the proposed algorithm can compensate for the power factor and suppress the harmonics of nonlinear loads. Finally, some experimental results are presented for verification.
