This paper proposes fuzzy logic controller based a single-phase seven-level inverter for grid-connected
photovoltaic systems, with a novel pulse width-modulation (PWM) control scheme. Three reference signals produces
from fuzzy logic controller which are identical to each other are going to compare with the amplitude of the triangular
carrier signal. The inverter is capable of producing seven levels( Vab = Vdc Vab = 2Vdc/3 Vab = Vdc/3 Vab = 0
Vab =−V dc/3 Vab= − 2Vdc/3 Vab = −V dc )of output-voltage levels from the dc supply voltage. The total harmonic
distortion is reduces by this control strategy. The proposed system was verified through simulation.
