IoT based Smart Bulb

This project deals with the design & analysis of the Microcontroller based Smart battery charger specifically designed for multimode operation to ensure no power cut. The main objective of this project is to provide uninterrupted power supply to a load by selecting the power supply from multiple sources such as Mains, Solar Power, Battery Bank and Generator automatically on the basis of their preference. The design and performance analysis of a power factor corrected (PFC), single switch forward buck converter proposes Smart Charger is carried out for low power battery charging applications. The main features of battery charger are low cost, fast charging, high power factor, high efficiency, minimum ripple and high reliability. The concept of this project is the combination of solar power inverter, wireless power transfer concept used for the generation of power and Internet of Things (IoT) based home automation system. The advantage of this project is to provide access to an everlasting and pollution free source of energy. This option is provide to use the system in two possible operating modes; the stand alone mode which is used to satisfy this needs, and the grid connected mode which used to sell electricity to utility when in excess; thus eliminating the need of battery storage.
