When the loads required harmonic, unbalanced and reactive power is beyond the limited capacity of a thyristor controlled LC-coupling hybrid active power filter (TCLC-HAPF), the TCLC-HAPF with the conventional control methods cannot provide satisfactory compensation performance. In this chapter, a selective compensation control method is proposed for harmonic distortion, unbalanced and reactive power of TCLC-HAPF. First, the proposed control method decomposes the load power into fundamental positive-sequence reactive power, fundamental negative-sequence power (unbalanced power) and harmonic power. Then, the decomposed harmonic, unbalanced and reactive power can be selectively or fully compensated based on the capacity of the TCLC-HAPF. Finally, simulation and experimental results are provided to verify the effectiveness of the proposed selective compensation control method for the TCLC-HAPF.
