Series active power filter implementation using P-Q theory

This paper deals with the design and implementation of series active power filter for power quality improvement. The problem of harmonics due to non-linear loads can be reduced by series active power filter. P-Q theory is used as the control algorithm in the proposed series active power filter. The performance of the filter is evaluated by monitoring the reduction of total harmonic distortion and the improvement of power factor. Finally, the series active power filter is simulated for hardware implementation using micro-controller and power electronic circuits.
