Presentation Transcript

Slide 1: 

WIRELESS ENERGY TRANSFER PRESENTED BY :- ULKESH KALANTRI RAJAN SAINDANE AKSHAY PATIL (E&TC 2 ND YEAR)

Slide 2: 

WHAT IS W.E.T ? The transmission of energy, from one place to another without using wires

Slide 3: 

HISTORY OF W.E.T :- The beginning Nikola tesla Wireless power transmission experiments at wardenclyffe

Types of W.E.T. : 

Types of W.E.T. 1.Short range. 2.Medium range. 3.Long range.

Slide 5: 

TYPES OF W.E.T :- 1 ] SHORT RANGE

Slide 6: 

2] MEDIUM RANGE

Slide 7: 

3] LONG RANGE :-

Slide 8: 

There are several methods to transfer electrical signals Methods of transfer electrical signals :- Electromagnetic induction Electrodynamics induction Electrostatic induction Laser method Microwave method

Slide 9: 

Electromagnetic induction Energy transfer by electromagnetic induction is typically magnetic but some inductive coupling can also be achieved.

Slide 10: 

2. Electrodynamics induction The wireless Electrodynamics induction transmission technique is near field over distances up to about one-sixth of the wavelength used.

Slide 11: 

3. Electrostatic induction The electric energy transmitted by means of electrostatic induction can be utilized by a receiving device, such as a wireless lamp

Slide 12: 

4. Laser method Recently developed solid state lasers allow efficient transfer of power Range of 10% to 20% efficiency within a few years Conform to limits on eye and skin damage

Slide 13: 

5. Microwave method Microwaves are received with about 85% efficiency Around 5km across (3.1 miles)

Slide 14: 

IMPORTANTACE OF W.E.T :- Conventional energy transfer is using wires . But , the wireless transmission is made from wireless technologies.

Slide 15: 

Several 20th century technology that use wireless power included AM, FM, and TV broadcasting Telecommunications and wireless internet Devices using this principle to charge portable consumer electronics This could include LEDs, computer peripherals, wireless sensors, and medical implants APPLICATIONS OF W.E.T :-

Slide 16: 

CONCLUSION :- The transmission of power without wires is not a theory or a mere possibility, it is now a reality. The electrical energy can be economically transmitted without wires to any terrestrial distance. Wireless transmission of electricity the system would reduce the cost of electrical energy.
