8. ◻ A Slayer Exciter is an air-cored transformer that
steps up a very low DC voltage to a very high AC
voltage.
◻ This creates an electromagnetic field around the
coil that is capable of lighting up fluorescent and
neon light bulbs.
◻ It is fairly similar to a Tesla Coil.
Basicworking
10. ◻ The power source supplies
the voltage and amperage.
◻ The driver circuit takes the
electricity from the power
source and prepares it for
the transformer.
11.
12. ◻ The primary coil creates a magnetic field from the electricity.
◻ The secondary coil converts the magnetic field back into
electricity and steps it up to a much higher voltage.
◻ Finally, the top load acts as a capacitor, greatly increasing the
strength of the electromagnetic field
14. 1. Highly Resonant Strong Coupling
Provides High Efficiency Over
Distance.
o This mode of wireless power transfer is
highly efficient over distances ranging
from centimeters to several meters.
o We define efficiency as the amount of
usable electrical energy created
from a source.
o This mode of transfer can
assure a high rate of efficiency
due to its design
15. o The magnetic near field has several properties that make
it an excellent means of transferring energy in a typical
consumer, commercial, or industrial environment.
o Most common building and furnishing materials, such as
wood, gypsum wall board, plastics, textiles, glass, brick,
and concrete are essentially “transparent” to magnetic
fields—enabling this technology to efficiently transfer
power through them.
o In addition, the magnetic near field has the ability to
“wrap around” many metallic obstacles that might
otherwise block the magnetic fields.
2. Energy Transfer via Magnetic Near Field Can
Penetrate and Wrap Around Obstacles
16. 3. Non-Radiative Energy Transfer is Safe for
People and Animals
o WiTricity’s technology is a non-Radiative mode of energy
transfer, relying instead on the magnetic near field.
o Magnetic fields interact very weakly with biological
organisms—people and animals—and are scientifically
regarded to be safe.
o Professor Sir John Pendry of Imperial College London,
a world renowned physicist, explains: “The body really
responds strongly to electric fields, which is why you can
cook a chicken in a microwave. But it doesn't respond to
magnetic fields.
o As far as we know the body has almost zero response to
magnetic fields in terms of the amount of power it
absorbs."
17. 4. Scalable Design Enables Solutions
from Milli watts to Kilowatts.
o This system can be designed to handle a broad range
of power levels.
o The benefits of highly efficient energy transfer over
distance can be achieved at power levels ranging
from Milli watts to several kilowatts.
o This enables the technology to be used in
applications as diverse as powering a wireless mouse
or keyboard (milliwatts) to recharging an electric
passenger vehicle (kilowatts).
