3. Existing problem
With mobile phones becoming a basic part of life, the
recharging of mobile phone batteries has always been a
problem.
The mobile phones vary in their talk time and battery
stand by according to their manufacturer and batteries.
 All these phones irrespective of their manufacturer and
batteries have to be put to recharge after the battery has
drained out.

4. Proposed Solution
The main objective of this current proposal is to make the
recharging of the mobile phones independent of their
manufacturer and battery make.
In this paper a new proposal has been made so as to make
the recharging of the mobile phones is done using
induction principle.

5. Introduction
This is based on Inductive charging uses an electromagnetic
field to transfer energy between two objects.
This is usually done with a charging station.
Energy is sent through inductive coupling to an electrical device,
which then can use that energy to charge batteries.
Because there is a small gap between the two coils employed in
each of the sender and receiver of the energy within the respective
devices, inductive charging is considered a short-distance wireless
energy transfer, despite the fact that there are typically more wires
used with inductive charging than direct-contact charging, because
it frees the user from having to deal with wires between the two
devices.

6. Aim of the project
This is based on Inductive charging uses
an electromagnetic field to transfer energy between
two objects. This is usually done with a charging
station.
Induction chargers typically use an induction coil to
create an alternating electromagnetic field from within
a charging base station, and a second induction coil in
the portable device takes power from the
electromagnetic field and converts it back into
electrical current to charge the battery.

8. Working
Here we using induction effect to charge the
mobile.
The mobile to be charged to be placed on inductive
generation coils.
The project is used in multiple ways such as in
securing the mobile from loss or theft as well as it gets
charged wirelessly.
If any one wants to steal it automatically a 60 Db
siren will get a switched ON. The system is provided
with a control switch it has to be made ON such as if the
user wants to charge mobile it will be placed on this
inductive plates .
Once the charging is completed if it is removed
without making the switch OFF automatically siren will

12. Power Supply
This project uses regulated 5V,9V 500mA power
supply.7805 three terminal voltage regulator is used for
voltage regulation. Bridge type full wave rectifier is used to
rectify the ac out put of secondary of 230/18V step down
transformer

13. Advantages
Fit & Forget system
Wastage of time can be reduced
Ease of operation
Reduce human effort
User friendly
No need to carry charger

14. Applications
 Inductive charging is used for implanted medical
devices that require periodic or even constant external
power, and for electric hygiene devices, such as
toothbrushes and shavers, that are frequently used
near or even in water. Inductive charging makes
charging mobile devices and electric vehicles

15. Conclusion
The project “Wireless Mobile Charger using
induction with anti-theft prevention system “ is
designed using advanced embedded technology.
The proposed method is verified to be highly
beneficial for all the Mobile phones.
