WIRELESS POWER TRANSFER

  1. 1. 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT 1
  2. 2. PRESENTED BY:ANKIT KUMAR (EEE/317/10) VIKASH KUMAR (EEE/267/10) PANKAJ KR. MEHRA (EEE/279/10) RAKESH KUMAR (EEE/290/10) SUBMITTED TO:PROF. VIKRAM SAXENA (PROJECT GUIDE) 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT 2
  3. 3. R.V.S.C.E.T. EEE DEPARTMENT 1/8/2014 CONTENTS :1. INTRODUCTION & HISTORY BY ANKIT KUMAR 2. INDUCTIVE RESONANCE COUPLING BY VIKASH KUMAR 3. CONSTRUCTION &OPERATION BY PANKAJ KR.MEHRA 4. APPLICATION & FUTURE BY RAKESH KUMAR 3
  4. 4. What is WitriCity? Witricity is nothing but wireless electricity. Transmission of electrical energy from one object to another without the use of wires is called Witricity. Because of Witricity some of the devices won’t require batteries to operate . 4 R.V.S.C.E.T. EEE DEPARTMENT 1/8/2014
  5. 5. Why we need Witricity?. WE USE WIRES… 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT 5
  6. 6. History of Wireless Power:  In 1899, Sir Nikola Tesla Proposed a method of Wireless Power Transmission.  As it is in Radiative mode, most of the Power was wasted and has less efficiency.  Able to light lamps over 25 miles away without using wires The team from Massachusetts Institute of Technology, who call their invention ‘WiTricity‘. In the first successful trial of its kind, the team was able to illuminate a 60-watt light bulb 7ft away. 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT 6
  7. 7. R.V.S.C.E.T. EEE DEPARTMENT 1/8/2014 TYPES OF WITRICITY Inductive Coupling Resonant Inductive Coupling 7
  8. 8. Inductive coupling • Primary and secondary coils- not connected with wires. • Energy transfer - due to Mutual Induction. 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT 8
  9. 9. Inductive coupling (contd…) • Transformer is also an example • Energy transfer devices are usually air-cored • Wireless Charging Pad(WCP),electric brushes are some examples • On a WCP, the devices are to be kept, battery will be automatically charged. 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT 9
  10. 10. Resonance Inductive Coupling(RIC)  Combination of inductive coupling and resonance  Resonance makes two objects interact very strongly 10 R.V.S.C.E.T. EEE DEPARTMENT 1/8/2014
  11. 11. How resonance in RIC? Coil provides the inductance  Capacitor is connected parallel to the coil  Energy will be shifting back and forth between magnetic field surrounding the coil and electric field around the capacitor  High resonant frequency  1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT 11
  12. 12.  RIC is highly efficient  RIC has much greater range than inductive coupling  RIC is directional when compared to inductive coupling  RIC can be one-to-many. But usually inductive coupling is one-to-one  Devices using RIC technique are highly portable R.V.S.C.E.T. EEE DEPARTMENT 1/8/2014 12
  13. 13. BASIC TECHNOLOGY :WORKING CYCLE Electricity Resonant Magnetic Coupling Magnetism Resonance Energy/Pow er Coupling 1/8/2014 Electromagn etism Magnetic Induction R.V.S.C.E.T. EEE DEPARTMENT
  14. 14. AIM OF THE CIRCUITS :- 1. 2. 1/8/2014 • CONVERTION OF NORMAL FREQUENCY TO HIGH FREQUENCY • CONVERTION OF INDUSED HIGH FREQUENCY TO NORMAL FREQUENCY R.V.S.C.E.T. EEE DEPARTMENT
  15. 15. CONVERTION OF LOW FREQUENCY INTO HIGH FREQUENCY :1. OSCILATOR 2. INVERTOR 3. INDUCTION COILS 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT
  16. 16. FIRST METHOD :USE OF OSCILATOR TO GENERATE A FIXED HIGH FREQUENCY 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT
  17. 17. SECOND METHOD :USE OF INVERTOR TO GENERATE REGULATED HIGH FREQUENCY 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT
  18. 18. R.V.S.C.E.T. EEE DEPARTMENT 1/8/2014 THIRD METHOD :- USE OF INDUCTION COIL WITH PROPER TUNING
  19. 19. TRANSMITER CIRCUIT :- BY MULTISIM 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT
  20. 20. RECIVER CIRCUIT:- 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT BY MULTISIM
  21. 21. COMPLETE BLOCK DYGRAM:- 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT
  22. 22.  No wires  Need for battery is eliminated  No e-waste  Efficient energy transfer  Harmless, if field strengths under safety levels  Maintenance cost is less R.V.S.C.E.T. EEE DEPARTMENT 1/8/2014 22
  23. 23.  Distance constraint  Field strengths have to be under safety levels  Initial cost is high  In RIC, tuning is difficult  High frequency signals must be the supply R.V.S.C.E.T. EEE DEPARTMENT 1/8/2014 23
  24. 24.  Electric automobile charging  Static and moving  Consumer electronics  Industrial purposes 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT 24
  25. 25. IN MEDICAL 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT 25
  26. 26. eliminating the need for disposable batteries or a power cord connecting the helmet 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT 26
  27. 27. 1/8/2014 R.V.S.C.E.T. EEE DEPARTMENT 27
  28. 28. IN CONSUMER ELECTRONICS 28 R.V.S.C.E.T. EEE DEPARTMENT 1/8/2014
  29. 29. Conclusion • • • • • • • 1/8/2014 Transmission without wires is possible Efficient Low maintenance cost. But, high initial cost Better than conventional wired transfer Energy crisis can be decreased Low loss In near future, world will be completely wireless R.V.S.C.E.T. EEE DEPARTMENT 29
