Abstract :
In this paper the control of the current-source active power filter is discussed. A new method for compensating the sampling and calculation delays of the digital control system is presented. The compensation in the proposed method is achieved using the regular LC filter of the active power filter as an energy storage for the load current and no additional components are needed in the main circuit. Furthermore, the calculation power demand of the proposed method is reasonably low and is therefore suitable for single-chip microcontroller implementations. The validity of the proposed control methods are verified by simulation
