Popis: This paper presents a novel Fuzzy Logic Controller (FLC) for regulation of output voltage in photovoltaic conversion stand alone two stages cascade. The voltage reference vector module of five levels NPC inverter constituting the second stage of proposed cascade is calculated each period after determination of the new modulation index using the proposed FLC controller. Knowing that the NPC topology suffers from the problem of unbalanced DC voltage, authors proposes to applied Space Vector Modulation (SVM) and use the 36 redundant vectors of five levels space vector diagram to regulate capacitors voltages. The second fuzzy logic Maximum Power Point Tracking (MPPT) controller designed to control the boost converter (first stage) is capable of extracting maximum power from PV array. The simulation results show that the RMS output voltage is inside the band of +/−10V and with low total harmonic distortion despite irradiation change.
