Energy Efficiency Optimization in PV Systems through the Implementation of Boost Converter Topology

Abstract

The performance of Photovoltaic (SPV) systems is greatly influenced by factors such as temperature, array configuration, solar insolation, and shade. The use of SPV modules to convert solar energy faces challenges due to changes in insolation conditions, which can affect the efficiency and output power of the modules. One way to improve the efficiency of solar energy conversion is to track the maximum power point of the PV module using the various Maximum Power Point Tracking (MPPT) charge controllers available on the market. The key component in an SPV is the dc-dc converter, which serves as the interface between the load and the SPV module. The use of this dc-dc converter can improve the performance of the MPPT algorithm, thereby improving the overall efficiency of the SPV system. In this study, modeling and simulation of the equivalent circuit of one diode of a solar photovoltaic module using MATLAB/SIMULINKTM was carried out, with the application of a boost converter that was able to achieve an efficiency of 93.29%.
