The document discusses wireless power transfer through inductive coupling. It provides block diagrams and descriptions of the transmitter and receiver circuits, which use a high frequency transformer, rectifier, and filter capacitors. The principle of mutual induction is used to transfer power across an air gap from the transmission coil to the receiving coil. Advantages are listed as low cost, compact size, and not requiring physical connections. Applications mentioned include charging mobile phones and powering medical devices wirelessly. Limitations include lower efficiency over long distances.

2. INTRODUCTION
 This is a special kind of transmitting of a power. In which
there is no need of any kind of communication wire to
connect the power supply. In this process where
electrical energy is transmitting from a power source to
an electrical load across an Air gap using induction coil.
From this circuit we can charge mobile or other devices
wirelessly in short range

5. Working Principle
 This circuit mainly work on the principle of
mutual induction. Power is transferred for
transmitter to receiver wirelessly based on the
inductive coupling.

13. -:Advantage:-
 Low Cost.
 Low Power consumption.
 Easy to install.
 Effective in battery less device.
 Compact
 Short circuit avoided
 Eco Friendly

14. -:Limitations:-
 Low efficiency For long distance electricity
transfer
 Losses or energy due to winding or coil

15. -:Applications:-
 Medical devices.
 Battery less passive devices.
 Mobile phone charging.
 Contact less activation and detection.
 Running low current devices.
----Wireless power transfer is used in ----

16. -:Conclusion:-
 In conclusion that Resonant Inductive
coupling power transmission would be
extremely beneficial to society if it is were
implemented in home and home electronics.
From an environmental stand point this
technology could repulsed disposable battery
and Cords. Reducing dangerous chemical
and potential for poisoning communities
resonant inductive coupling has also health
benefiter

17.  Some people worry about health risks of
being exposed to the magnetic field coursed
by the resonant inductive coupling
 Many people see the huge benefit offer by
resonant coupling there are the medical
patent who can be help with this technology
 The limitation of the wireless power grandly
outweighed by the benefit and from an ethical
standpoint thus it is necessary further
developed wireless power technology to the
point large scale production
