INTRODUCTION
The transmission of power from one place to another without using wires, cables or chords.
Due to increasing number electronic devices in our daily life such as laptops, digital cameras, household robots, etc.
All these devices are powered by batteries, which need to be recharged very often.
So what if we could enable wireless powering of these and similar devices?
History of Wireless Power:
In 1899, Sir Nikola Tesla
Proposed a method of Wireless
Power Transmission. As it was a
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.
One Simple Physics Rule !
At Source : Electricity → Magnetic Wave
At Device : Magnetic Wave → Electricity
