Abstract

In this paper, the seven-level cascaded type inverter is used as a shunt active power filter to exploit multilevel inverter advantages. The capacitor voltage control technique used as a harmonic current extraction method for the two-level inverter is extended to the seven-level shunt active power filter. A predictive current controller based on the supply current (not the active filter current) is applied. Phase-shifted space vector modulation for the multilevel inverter is used as a PWM technique. The proposed seven-level shunt active power filter is validated by simulation.
