Smart Mobile Charger
Mobiles are used now a days everywhere. Electricity is required to charge the mobile battery. we use mobile chargers to charge the mobile using 220 Volts AC. some time 220 Volts AC is not available. like during driving or in rural areas where electricity is missing for many days. We can’t use Dc voltage directly to charge the mobile, as mobile chargers are costant current chargers.
Travelling mobile chargers are developed by some companies to overcome this problem. they can be fitted in cars to charge mobile. but such type of chargers can charge a specific mobile only . As there are many types of mobiles in the market , we require many types of travelling chargers.
Here we are designing a different project. We will generate 220 Volts AC from 6 volts DC. And using this 220 Volts AC a person can charge his mobile with his own mobile charger and different types of separate DC Mobile chargers are not required.
For this purpose we require a Inverter circuit. As conventional inverter circuits are very complicated and their prices varies from thousands . here we will develop a very simple circuit which works well for charging mobiles.
Application :
• We can charge any company mobile like nokia,samsung,Tata,sony ericssion etc.
Futer Enhancce:
• Generally we create a low watt capacity inverter,further we can also increase the capacity of inverter like 600watt,7000watt etc.The inverter convert dc voltage into ac voltage.
