An a-b-c Reference Frame-Based Compensation Strategy for Series Active Power Filter Control

This paper presents a new control strategy to determine the reference compensation voltages of a series active power filter (APF) operated under non-ideal supply voltages in the steady state. With using the proposed control strategy, the load-side voltages can be maintained being sinusoidal and balanced. The effectiveness of the proposed control strategy is demonstrated through simulations by using Pspice. Results show that the expected series APF performances are achieved with adopting the new control strategy
