Abstract

The three-phase, three-wire, five-level cascaded Inverter is used as a medium-voltage shunt active power filter. The capacitor voltage-control technique used as a harmonic current extraction method for the two-level inverter is extended to the five-level shunt active power filter, with a technique proposed for balancing capacitor voltages. Predictive current control based on the supply current (not the active filter current) is employed. Two different space vector modulation (SVM) techniques viz., phase-shifted SVM and hybrid SVM, are used for multilevel inverter pulsewidth-modulation generation. The proposed five-level shunt active power filter is validated by simulation and practically for both modulation techniques. The proposed technique results in the same software and hardware requirements for any m-level inverter.
