Abstract

In this paper investigations are made with different maximum power point tracking (MPPT) techniques for a photovoltaic
generator (PVG). The PVG is used to supply an induction motor driving a centrifugal pump. Boost converter and inverter are
connected in between PVG and motor for power conditioning. Three MPPT techniques are designed and compared. These
techniques are incremental conductance (IC), constant voltage controlled (CVC) and fuzzy based perturbation and observation
(FPO). Rule Base of FPO is designed with nine rules only, so that it can be implemented on limited memory and speed
processors. System performance is analyzed with the help of developed simulation models. A comparative study of these
techniques is also summarized. The obtained simulation results indicate that FPO scheme yields better performance.
