Abstract: Performance of an active power filter mainly depends on the accurate generation of the reference current. The most commonly used method is the instantaneous PQ theory based reference current generation scheme. Although it is advantageous in many aspects, it fails to achieve desirable compensation results under unbalanced supply voltage condition in three-phase electrical power systems. Therefore this issue is addressed in this work and a suitable improved version of Instantaneous PQ theory is presented. The proposed theory is validated by the results obtained through simulation-based studies.
