Comparative Study of MPPT Nonlinear Controller, Using Boost Converter for PV Modules
Authors: , ,
Abstract: Due to nonlinear I-V characteristics of photovoltaic cells, a maximum power point tracking algorithm is adopted to maximize the output power. In this paper, an approach for peak power tracking using the nonlinear controllers (Sliding mode and fuzzy logic) is proposed. These controllers are Compared with the conventional duty cycle of perturb and observe (P&O) control method, they can track the maximum power point quickly and accurately. Matlab-simulink is used for simulation, analysis and interpretation the results of these controllers. A boost converter has been used to control the solar cell output voltage.
