Implementation of a new MPPT Technique for PV systems using a Boost Converter driven by Arduino MEGA

The present paper aims to propose an implement of perturb and observe (P&O) technique for photovoltaic systems using a boost converter driven by Arduino MEGA 2560 in a view of providing an efficiency improvement of PV system. This method has been further characterised by considering its fast ability of tracking the (MPPT) and reducing the computational time using digital controls of the Arduino MEGA 2560 microcontroller. In the present paper, we proposed a simple method for implementing the P&O technique by interrupts of the Arduino MEGA. Indeed, the (P&O-MPPT) technique implementation technique has been carried out with regard to the usage of the developed costless instruments. oreover, the regulation of (P&O) MPPT technique which is responsible for the switching of MOSFET exists in the dc-dc boost converter so that it can extract the MPP. This work has been therefore simulated by Matlab/Simulink and programing by C code, and consequently, in a view of the above, the (P&O) algorithm has been applied in a real time by Arduino MEGA to decrease the cost of the MPPT controller and to show the results of the performance for the proposed technique.
