Design and implementation of solar docking station for smartphones/laptops

Abstract Presently the innovation has developed to a momentous level that a student’s learning process happens through smart phones and laptops called Mobile e-leaning. Experiencing the outdoor and open spaces can benefit a student’s emotional, social and physical improvement. The difficulty in extending multiple power chords in open spaces and in locations where the access to electrical power outlet is arduous has prompted the idea of photovoltaic based solar charging/Docking station for charging mobile phones and Laptops. A remarkable impedance source inverter is implemented for the solar docking station and its performance is enhanced by implementing hybrid pulse width modulation technique. The components such as solar panels, rechargeable batteries, and charge controller pertaining to the installation of solar docking station are designed by analysing the load applied through AC and USB charging ports and the backup time requirement. A solar docking station is successfully installed in the college campus with the proposed inverter for charging the laptops and mobile phones.
