Abstract :
This paper proposes a controller implemented in a current-source active power filter (CS-APF) which can adjust adaptively the reactive power generated by the APF. With this controller, the line current distortion level can be kept within a certain limit whilst the system power factor can be maintained at a highest available level. In an APF with DSP-based controller, the proposed algorithm can be implemented with some modification in the controller software only. Performance of a CS-APF with and without this adaptive controller are simulated and compared to show the validity of the proposed approach.
