DESIGN AND IMPLEMENTATION OF MAXIMUM POWER POINT TRACKING (MPPT) SOLAR CHARGE CONTROLLER

Abstract

In the context that fossil fuel resources are increasingly exhausted, environmental pollution and climate change are becoming more and more serious, while the load continues to increase rapidly, the demand for power sources for development is increasing. Therefore, the exploitation of solar power is even more important in terms of ensuring electricity supply. Researching to design and implement the maximum charging circuit for solar power system. Solar power is becoming more and more widely used, however, one of the disadvantages of the solar power source is that it requires storage devices like batteries. For optimal battery charging, a charging control circuit is required. This project was done by using simulation and construction testing methods. The charging circuit is designed on Proteus software, programmed and after construction tested at Thu Dau Mot University. The circuit has operated stably, tested with a 20W battery, 12 V - 5Ah battery. The results of the study help to provide the optimal solution for the exploitation of solar energy, effectively serving the energy production process.
