High Performance DC-DC Converter for Low Voltage Standalone Solar PV Systems

摘要

The energy available from the sun is purely renewable source of energy and it is freely available in this nature. Solar Photovoltaic frameworks have risen as a noteworthy resource to serve as a main source. The majority of the sunlight based Photovoltaic frameworks require a dc to dc converter with increased gain and efficiency. Typical converters which can offer constrained/controlled gain and their productivity drops as the increased necessity increments. This project proposes a three phase off-grid Photovoltaic framework those utilizations dc to dc converters having high gain and increased efficiency in the forward power stage. For battery interfacing Bidirectional converter which converts dc to dc from one level to desired level is most used and required device in case off-grid Photovoltaic frameworks. The utilization of low voltage photovoltaic system and battery system are worked by converters in which the gain and efficiency are increased. Maximum Power Point Tracking technique is utilized to extract maximum power from solar panel by managing the DC bus voltage and satisfying the power requirement. All the simulation results of this paper are presented. The Complete model is developed and simulated using MATLAB / Simulink environment. Based on the proposed system mathematical & electrical model is developed.
