Abstract

In this paper, the amalgamation of three input power sources as a charging tool for phones and low power communication devices is presented. The developed system comprises a human powered dynamo, solar panels to harvest energy from the sun and a rechargeable battery supply. A simple switching mechanism is incorporated to switch between respective sources. A common dc-dc regulation circuit adjusts the vacillating input voltages to satisfy phone and communication device charging voltage specification. The multi-source system eliminates the effect of periodic variation and unavailability of any of the input sources in event of a need for emergency device charging and demonstrates the potential to power or charge a phone.
