PHF is kind of low-pass harmonic filter to help improving harmonic currents, so that the total THDI and THDV can meet the limits of IEEE519,and the power factor can reach above 0.95 at 100% loading. There is no resonance between PHF and system power. The input capacity can be switching in different groups according to the load request, to avoid the over compensation and under compensation of power factor.
