  1. Wireless Power Transmission The team: Andrew McKay George Bucsan Nir Neerman Peter Dowling Prof. Carolann Koleci PH 1121 E&M

  2. Summary What? Wirelessly transmit power How? Electromagnetic Induction With what? 2 Coils and a term’s worth of PH1121 Goals? Light up an LED from 10cm without wires

  3. First Wireless Transmitter • Nikola Tesla • 1891 • Columbia College • American Institute of Electrical Engineers

  4. Concept Power supply => AC current AC current & inductor => Varying field Varying field = Varying flux Varying flux & inductor => induced AC AC current + RLC = Power RLC + optimal frequency => resonance Resonance => Higher Intensity

  5. Theory Parameters: • Coil 1 : N1=10 windings, radius a=2.9 cm, L=10cm • Coil 2 : N2=75 windings, radius b=4.2 cm, L2=6cm • Power Supply: Vinput=0.25V • Capacitor: C=0.01µF • Led’s: Rled=66Ω • Inter-coil distance: z=5cm

  6. Equations: • Coil 1 inductance • Coil 2 inductance • R&C Resonant Frequency

  7. Pulsation, ω • Coil 1 Current • Magnetic field at z

  8. Output Voltage • R&C Impedance • LED Current

  9. Predictions

  10. Practice Building the device: • Laser cut acrylic • Magnet wire • Circuit board • LED’s • Capacitor

  11. Applications Wireless charging: Powermat Wirelessly powering appliances: Wireless TV

  12. Special Thanks • Rob Lowry • Fred Hutson • Tom Angelotti • Neil Whitehouse • And of course, Prof. Koleci  References: Halliday Walker Resnick – Fundamentals of Physics
