INTRODUCTION

The percentage of loss of power during transmission and distribution is approximated as 26%.

Tesla has proposed method of transmission of electricity using electro magnetic induction

What is witricity? Transmission of energy to air Process of transferring electrical energy or power over

distance without using wires also known as witricity or wireless power transmission

batteries for transmission of power

WHY TO USE WITRICITY??

HISTORY

Sir NICHOLAI TESLA was the first one to propose and research the idea of wireless transmission in 1899

Tesla enlighten 200 lamps at he distance of 40km but only 15% efficiency was achieved.

Basic Principle:Magnetic resonance.

Types of wireless energy transfer techniques

Short range– Inductive coupling Mid range– Resonance Inductive couplingLong range- Electromagnetic Wave Power Transfer

Witricity works on the principle of mutual induction between the two coils.

There are two copper coils arranged one at the sender end and other at the receiver end .The first coil is attached to the power source while the second coil to the light bulb.

When the power is switched on the first coil converts the electricity into magnetic field ,which is oscillating at a particular frequency i.e, AC source.The second coil at the receiver end converts the magnetic field into electricity . The surrounding environment is unaffected.

WORKING PRINCIPLE

HOW DOES RESONANT INDUCTION WORKS

Same principles as magnetic induction, but uses resonance to increase the range.

Everything resonates at a certain frequency, based on its shape and material.

Energy transfers easily between resonating objects. With resonant induction, power is transmitted

between two resonating coils.

ADVANTAGES

Safe, fairly efficient, good ranges More secure, no risk of getting shocked Maintenance cost will be saved Non-radioactive energy transfer is safe for people

and animals. Wastage of power is less. No need of power cables, batteries, e-waste and line

of sight

Wireless power transmission can be possible only in few minutes

Need for standardization and adaption.so a little overheating occurs because of different voltages

Refitting old equipment's or purchasing new equipment's could become a very expensive endeavour

Possibility of “energy theft”. Wi Fi, someone can be using your internet or your power.

Disadvantages

Consumer electronics transportation

APPLICATIONS

CONCLUSION

think that city will be covered with WPT hot spots , just like Wireless Internet, there will be no need of charging batteries or carrying adapters all around Wireless power transfer is quickly becoming a viable reality.
