Introduction

WHAT IS WIRELESS POWER TRANSMISSION?

Problems solved

  • No Tangled Wires
  • No need for electrical sockets
  • Decreases energy loss during transmission

qualities

  • Reliable
  • Fast
  • Efficient
  • Low Maintainence

Combination of inductive coupling and resonance

Resonance makes 2 objects interact very strongly

Resonance in RIC

  • Coil provides the inductance
  • Capacitor is connected parallel to the coil
  • Energy shifts back and forth from magnetic and electrical field
  • Radiation loss will be negligible

Near field Energy transfer

Advantages of near field techniques

  • No Wires
  • No e-waste
  • No need for battery
  • Efficient energy transfer using RIC
  • Harmless and Low Maintenance Cost

Disadvantages of near field techniques

  • Distance Constraint
  • Field Strength have to be under safety levels
  • Initial cost is high
  • In RIC, tuning is difficult
  • High Frequency signals must be high

far field energy transfer

  • Radiative
  • Needs Line of Sight
  • Uses LASER of Microwave
  • Aims at high power transfer
  • Tesla Tower was built for this

advantages of far field energy transfer

  • Efficient and Easy
  • No need for grids and substations
  • Low Maintenance Cost
  • Can reach remote areas
  • Effective when transmitting and receiving end are along a line of sigh

Disadvantages of far field energy transfer

  • Radiative
  • Needs line of sight
  • Initial Cost is High

Applications

that could change the world
