This paper presents a space vector pulse width modulation (SVPWM) control for a five-level five-phase cascaded H-bridge multilevel inverter (CHMLI) for photovoltaic (PV) systems. The maximum power point tracking (MPPT) is solved by fuzzy logic controller (FLC) and it is capable of extracting maximum power from PV array connected to each DC link voltage level. The fuzzy MPPT is integrated with the inverter so that a DC-DC converter is not needed and the output shows accurate and fast response. This is done to achieve high dynamic performance with low total harmonic distortion (THD). The simulation results are compared with sinusoidal pulse width modulation (SPWM) controlled CHMLI and diode clamped multilevel inverter (DCMLI) in terms of THD. The results prove the viability and verify the effectiveness and accuracy of the proposed system.
