Abstract(s)This paper presents a shunt active filter with a controller able to dynamically limit the output current, which allows an effective protection of the inverter semiconductors without diminishing the active filter performance. The control strategy is based on the p-q theory expanded for three-phase four-wire systems and the power stage of the active filter is composed by a two-level four-leg inverter. Simulation results on PSCAD/EMTDC trade are presented to demonstrate the performance of the dynamic current limitation.
