Design of a Solar Battery Charger with Maximum Power Point Tracking

In recent times, an immense amount of effort is put into moving from conventional sources of energy to renewable sources of energy, such as solar, wind, hydroelectricity, and so on. Solar energy is more advantageous in comparison to other sources due to lower maintenance costs and reduced plant size. However, due to the large variation in irradiance, generating power efficiently from the solar panel is a challenge. A suitable MPPT algorithm can be implemented to increase the power obtained from the solar panel. This paper describes the design of a solar battery charger that utilizes a buck converter with the duty ratio controlled based on the Perturb and Observe MPPT algorithm.
