This paper proposes a new current control method suitable for an active power filter (AF). It requires only detecting the source current. It requires neither detecting AF output current nor extracting a harmonic component from the source current Thus, the current control system can be greatly simplified compared to conventional load current detection AF. This paper introduces an adaptive digital filter (ADF) with a synchronized filtered-x (SFX) algorithm. An SFX-ADF based current controller… CONTINUE READING
