| Abstract |
In this paper a parallel hybrid filter is studied for current harmonic compensation. The hybrid filter is formed by a single tuned LC filter per phase and a small-rated power three-phase active filter, which are directly connected in series without any matching transformer. The required rating of the active filter is much smaller than a conventional standalone active filter would be. No additional switching-ripple filter is required for the hybrid filter because the LC filter functions not only as a harmonic filter but also as a switching-ripple filter around 10 kHz. Simulation results and experimental results obtained in laboratory confirmed the validity and effectiveness of the control. |
