Simulation and study of photovoltaic cell power output characteristics with buck converter load

摘要

This paper present the study of photovoltaic cell (PV Cells) output power characteristics by experimenting with the simulation of equivalent circuit and of output behavior of photovoltaic while connected to the buck converter, with adjustment of its duty ratio (D). Experimental result show that the maximum power point (MPP) is reduced 24 %, while connected to the buck converter load compared with the linear load (resistor). The simulation results from MATLAB / Simulink program have a good agreement with the experimental.
