2. What is Wireless Charger?
• Inductive charging (also known as "wireless
charging") uses an electromagnetic field to
transfer energy between two objects.
• 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

4. Why Wireless Charger?
• Protected connections - no corrosion when the
electronics are all enclosed, away from water or
oxygen in the atmosphere.
• Safer for medical implants - for embedded
medical devices, allows
recharging/powering through the skin.
• Durability - Without the need to constantly plug
and unplug the device, there is significantly less
wear and tear on the socket of the device and the
attaching cable.

5. Inside the Wireless Charger
• Components of Wireless Charger

7. Circuit Diagram

8. Qi Interface
• Qi (pronounced "Chee") is an interface
standard developed by the Wireless Power
Consortium for inductive electrical power
transfer over distances of up to 4 cm (1.6
inches).
• Mobile device manufacturers that are working
with the standard
include Asus, HTC, Huawei, LG
Electronics, Motorola Mobility, Nokia,
Samsung, BlackBerry, and Sony.

9. Future Scope
• The energy loss can be minimized to bring out
the potential.
• Can be used in hotels, restaurants and other
public places
• Robust Interface
• Detailed Documentation and Specs to be
specified.

10. That’s all folks
