A shunt active power filter (APF) with current detection at the source side is considered as a closed-loop system from the view of the whole power distribution system, which is expected with better harmonics filtering performance compared with the one with load current detection. The conventional source current detection control scheme can be mainly grouped into two types: 1) current-source-based...
Compared to traditional load current detection type Active Power Filter (APF), source current detection type APF belongs to closed-loop control in control theory, which can improve its filtering performance dramatically. At first, this paper introduces two conventional APF control schemes with source current detection-proportional control and non-harmonic detection control. By analyzing, we points...
