Abstract

An intelligent fuzzy method for maximum power point tracking (MPPT) of photovoltaic (PV) systems is presented in this paper. In this method, fuzzy inference process can be finished by an equation with an adaptive factor instead of fuzzy rules lookup table, which saves memory space and accelerates operation process. It is simple to be implemented on single chip. The availability and adjustability of this method is validated by experiments using PV arrays, boost converter and single-phase grid-connected inverter. The simulation and experiment results showed its attractive features such as simplicity, fast response, well dynamic performance and that it can increase output power extracted from PV arrays.
