2. TESLA COIL
A Tesla coil is an electrical resonant
transformer circuit invented by Nikola
Tesla around 1891.It is used to
produce high-voltage, low-current,
high frequency alternating-
current electricity.
3. SLAYER EXCITER TESLA COIL
It’s a coil which gives
the wireless power
transmission.
coil consist of primary
(600 turns) & secondary
(3 turns) and high
frequency circuit (50-100
khz) for induction. Supply
source is dc (12 volt).
4. WORKING PRINCIPLE
• Faraday's law of magnetic induction, is
as follows: The EMF induced in a circuit
is proportional to the time rate of
change of the magnetic flux linking
that circuit. There are many different
ways in which the magnetic flux linking
an electric circuit can change.
• MAGNETIC FLUX:- Magnetic flux is the
number of magnetic field lines passing
through a closed surface (such as a
conducting coil).
6. MY IDEA
We can make a lamp which consist of a lots of
fluorescent bulb even if they are fuse they will glow
if we bring bulbs near to coil and it gives the
sufficient power to glow fluorescent bulb with just a
less than 100 bucks.
7. PRACTICAL EXAMPLE
In South Korea, first Wireless
Charging Powers Electric Buses
“The Korea Advanced Institute of
Science and Technology (KAIST)
developed the Online Electric
Vehicle (OLEV) platform”
8. First Wireless Charging Powers
Electric Buses
Its the same technology used to charge phones
wirelessly, but used on a much larger scale. In public
transit, induction relies on magnetic charge plates
beneath roadways and a counterpart inside the bus.
When an induction-capable bus passes over that
charging plate, the two magnets become “tuned,”
and current flows to charge the on-board battery
with a 6.7-inch gap between the road and the bus,
there’s 85% charging efficiency at 100 kW from the
road to the bus.
