Microcontroller Based Solar Charger

Abstract

This project is developed for the users to use portable solar cell phone charger. It consists of three modules. They are Solar panel, Inverting section and Cell phone charger. The solar panel converts solar power into electric power. The electric power is stored in a battery. The inverting section consists of two ICs CD4047 and ULN2004. It converts DC to desired AC. The step up transformer steps up 12 V AC to 230 V AC. The user can use any type of cell phone charger since it uses 230 V AC for its operation. This project is cost effective and portable. The user can take this while traveling.
