    • WITRICITY - wireless electricity Submitted By RADHIKA,NAVATHA
    • In this paper.... 1) History of Wireless power. 2) Need of Witricity. 3) Basic Principle. 4) Range & Rate of Coupling. 5) Design of Parameters and Simulation. 6) Pros and Cons.
    • WITRICITY
    • 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.
       The efficient midrange power transfer concept is Witricity. In this model source and load are in Magnetic resonance so there is no power loss.
    • RESONANCE COUPLING A group of engineers at MIT came up with the idea to use resonant induction to transmit power wirelessly. “Resonance", a phenomenon that causes an object to vibrate when energy of a certain frequency is applied. The forgotten invention is reborn in 2007
    • Need of Witricity: Now a days there is a Rapid development of autonomous electronics like Laptops , Cell-phones , House-hold robots and all those devices typically rely on chemical energy storage(Battery) As they are becoming daily needs to present generation, Wire less energy transfer would be useful for many applications as above and they need midrange energy.
    • What is Witricity?
      • Electricity without wires
      • Magnetic loop antennas
      • Electromagnetic near-field
    • How does Witricity Work?
      • Near-field inductive coupling through magnetic fields
      • Interact weakly with surrounding objects (biological tissue)
    • Witricity Today
      • MIT powered 60 watt light bulb from 2 meters (7 ft) at 40% efficiency
      • MIT researchers working on improving the technology
    •  
    • Witricity Tomorrow 1) Power from mains to antenna, which is made of copper 2) Resonates 10MHz (electromagnetic waves) 3) Tunnel up to 2m (6.5ft) 4) Electricity received by antenna, also resonating at 10MHz. 5) Energy not transferred to laptop re-absorbed by source antenna. People/other objects not affected as not resonating at 10MHz
    • Basic Principle: The basic principle involved in Witricity concept is, Two objects having same resonating frequency and in Magnetic resonance at Strongly coupled regime tend to exchange energy , while dissipating relatively little energy to the extraneous off-resonant objects.
    • Experimental Design: Our experimental scheme consists of two Self-resonant coils. One coil (source coil) is coupled inductively to an oscillating circuit; the other (device coil) is coupled inductively to a resistive load. Self-resonant coils rely on the interplay between distributed inductance and distributed capacitance to achieve resonance.

    • Advantages:
      • Unaffected by the day night cycle, weather or seasons.
      • This is an eco friendly system..
      • It is boon for the devices which uses midrange power.
      Limitations:
      • The resonance condition should be satisfied and if any error exists, there is no possibility of power transfer.
      • If there is any possibility of very strong ferromagnetic material presence causes low power transfer due to radiation.
