WIRELESS CHARGER

4. WHAT IS WIRELESS CHARGER

Type of wireless power transfer.

Multiple device can charged.

Simple structured and intuitive to use.
+ Electromagnetic fields to study

transfer power for the purpose
of charging.

WIRELESS CHARGER

5. COMPONENTS

= Transmitter
= Receiver
= Recteena

6. TRANSMITTER

= An electronic device
which produces radio waves with
the help of antenna.

= used for the radio communication of
information over a certain distances.

WIRELESS CHARGER

7. RECIEVER

= A device that receives a electrical sigr
waves or the like renders
them to perceptible to the
senses, as the part of a
telephone held to the ear,
radio receiving set or televi
receiving set.

WIRELESS CHARGER

8. RECTENNA

= Special type of antenna that is
used to convert electromagnetic
energy into direct current
electricity.

Used in wireless transmission
systems that transmit power by
radio waves.

9. TYPES OF WIRELESS CHARGING

= Resonance charging
= Radio charging
= Inductive charging

10. WORKING OF WIRELESS CHARGER

= Based on the principle of a magnetic
resonance or inductive resonance reg
(IPT-inductive power transmission) the pri Pe
is transferred between two objects > ciente
through coils.

In this charging there is no physical
connection between the transmitting on con
and receiving device.

11. ADVANTAGES

Less cords.

Universal compatibility.
Safe connections.

More durable.

No heating.

Safer for medical devices.

WIRELESS CHARGER

12. APPLICATIONS

Electrical cars
Laptops

Mobiles

Robots

Home appliances
Watches

Future development in this wireless charger technology like witricity will allow

charging og car batteries, household equipments, medical devices and other
devices to charge wireless instead of lots of wires and sockets.

WIRELESS CHARGER

13. CONCLUSION

Research to using wireless technology to supply to terminals is finally beginning
to be realized. The technology provides a wide range of other obvious benefits,
including better portability and best of all the end of having to guess which
charger go what gadgets. Charging will one day become a simple matter of
dropping devices into the nearest charging pad.
