Solar controller charge design

Due to the increasing use of renewable energy and economic efficiency of this type of energy, having an efficient charge controller to control the system and increase productivity is important. Charging control in solar panels prevents the battery from overcharging and thus increases battery life. It also prevents the electric current of the batteries towards the solar panels during the night.The two most common types of charge controllers are PWM charge controllers and MPPT charge controllers, which charge MPPT controllers more efficiently than PWM charge controllers. Charging MPPT controllers tracking the maximum power point using various methods. Conventional methods for tracking the maximum power point are: perturbation and observation, incremental conductivity, constant voltage, short circuit current, fuzzy logic control and artificial neural network.In this paper, by examining the existing methods, a model for designing a charge controller was proposed. The charge controller design based on MPPT method was selected and fuzzy logic control method was used to track the maximum power point.The proposed model for designing the charge controller was simulated in MATLAB software and its results are displayed. The results obtained are from four stages with different intensities of radiation and temperatures.
