A Wide Range Fuzzy Based Maximum Power Point Tracker for Improving the Efficiency and Sizing of Pv Systems
نویسندگان
چکیده
This paper presents a wide range maximum power point tracker (MPPT) using fuzzy logic controller for PV sizing and efficiency improvement. The MPPT consists of a buck boost converter, controlled by a fuzzy logic. The fuzzy has two inputs and single output. Inputs are voltage and current of the PV, while the output is duty cycle for the buck boost. The MPPT effectively tracks at average 97.3% of the peak power under wide range of solar irradiances and load resistances. Without MPPT, the PV output generates at average 67.7% of the peak power. A sizing method of PV system involving MPPT for supplying 2500 Watt load is also presented in this paper.
