In this paper, the three-level cascaded inverter is used as a shunt active power filter, making use of the multilevel inverter advantages of better total harmonic distortion, reduced semiconductor switches ratings, and reduced switching losses. A capacitor voltage control technique previously used as a harmonic current extraction technique is extended to the three-level shunt active power filter. Predictive current control based on the supply current (not the active filter current) is proposed. Three-level space vector modulation is used as a pulse width modulation technique. The proposed three-level shunt active power filter is validated by simulation using MATLAB/SIMULINK and practically with a laboratory prototype.
