To extract maximum power from PV system, many MPPT techniques have been employed by the researchers. This paper presents a fuzzy logic based MPPT algorithm for a 100 kW PV system. The Duty Cycle of the DC-DC boost converter is controlled by the proposed fuzzy MPPT control technique and hence maximum power is obtained from PV system. Simulations were carried out and the proposed MPPT technique is tested under different environmental conditions. The proposed method is effectively tracking the maximum power for all environmental conditions.
