project aims
Project Aims
  • Get the best efficiency from the inductors provided.
  • Investigate the effects of shielding on the system.
  • Build a working prototype of a wireless charging platform.
wireless power transfer
Wireless power transfer
  • Use of inductors.
  • Electric current flowing through a primary coil creates a magnetic field that acts on a secondary coil producing a current within it.
  • As the distance between the two coils increases, the system becomes very inefficient.

Application
  • Phone charging.
  • Reduce the need for plugs.
  • Save time.
  • No wires.
  • Don’t need to remember to charge devices.
