Resumo

The hybrid active harmonic filters use a series capacitor in order to reduce the voltage rating of the inverter compared to regular inductive-coupled active filters. Different control strategies are applied on this topology in the literature. The main contribution of this paper is to apply a H-infinity controller in order to achieve current tracking in voltage source inverters connected to the grid through a series LC coupling impedance. The primary goal of this control system is to track a harmonic reference current, in order to address power quality issues on the grid. An overview on the controller synthesis process is given. The discretization process is shown together with the controller robustness investigation using mu-analysis. Finally, the simulations are validated through experimental measurements using the synthesized controller. (AU)
