Variation of the Speed of a DC Motor Powered by the Photovoltaic Generator Using MPPT Control

This paper presents the analysis, modeling and control model of the electrical part of a photovoltaic generation system, connected to the DC motor by a Boost converter using MPPT control. Initially, we carried out a detailed study of the direct current motor with its characteristics, then we developed a mathematical model of the Photovoltaic Module where it is necessary to take meteorological data (irradiance and temperature) as input variables, the current, voltage or power as output variables. The model predicts the behavior and characteristics of the PV module based on the equivalent circuit of the mathematical model using the Matlab/Simulink platform under different temperatures and solar radiation readings. Then, a basic circuit of the boost converter is designed with constant DC source voltage, in the third step, a comparative study was also carried out for the converter connected to the PV system directly with the converter connected to the load (the motor has direct current) powered by the pulse generator. Therefore, the design of the model with the contribution of the boost converter, which responds to the use of systems aimed at increasing the input voltages and providing the loads with the desired outputs, leads us to suggest the efficiency and the use of this model.
