ABSTRACT
In the present day, electricity is one of the basic requirements for human
beings. But, the process of generating electricity is hazardous to the
environment. According to the energy information records
approximately 50% of all electricity plants are contaminating coal plants.
Various changes in the environment have been seen over the past thirty
years, which are injurious to the forthcoming generations of this planet.
To overcome this, here is a solution to diminish greenhouse gas
emissions into the atmosphere through an alternative power generation.
One sustainable technology leading this charge is WPT (wireless power
transmission)
The project is a device to transfer power generated by the help of solar
panels wirelessly instead of using conventional copper cables and
current carrying wires. The concept of wireless power transfer was
introduced by Nikolas Tesla. This power is made to be transferred within
a small range only for example charging rechargeable batteries etc.
WORKING PRINCIPLE
Solar panels are used to generate the electricity and the power which is
then transferred wirelessly. Solar power is a clean, infinite and
renewable source of energy and is the future of electric power for us.
The basics of wireless power transmission includes the inductive energy
that can be transmitted from a transmitter coil to a receiver coil through
an oscillating magnetic field. The DC current supplied by a power source
is changed into high frequency AC current by particularly designed
electronics built into the transmitter.
In the TX (transmitter) section, the AC current increases in the copper
wire that creates a magnetic field. Once the RX (Receiver) coil is moved
close to the magnetic field, then the magnetic field can induce an AC
current in the receiving coil. Electrons in the receiving device, converts
the AC current back into DC current that becomes working power.
To accomplish this, power source (DC current) is changed into high
frequency AC (Alternating Current) by particularly designed electronics
erected into the transmitter. The AC boosts a copper wire coil in the
transmitter, which produces a magnetic field. When the receiver coil is
placed in proximity of the magnetic field, the magnetic field can make an
AC (alternating current) in the receiving coil. Electronics in the receiving
coil then alters the AC back into DC which becomes operating power.

ABOUT WIRELESS POWER TRANSFER
Wireless power transfer (WPT) or wireless energy transmission is the
transmission of electrical energy from a power source to an electrical,
such as an electrical power grid or a consuming device, without the use
of discrete human-made conductors.
Wireless power techniques fall into two categories, non-radioactive and
radioactive. In non-radioactive techniques, power is typically transferred
by magnetic fields using inductive coupling between coils of wire.
Applications of this type include electric toothbrush chargers, RFID tags,
smartcards, and chargers for implantable medical devices like artificial
cardiac pacemakers, and inductive powering or charging of electric
vehicles like trains or buses
ABOUT SOLAR POWER
Solar power is the conversion of sunlight into electricity, either directly
using photovoltaic (PV), or indirectly using concentrated. Photovoltaic
convert light into an electric current using the photovoltaic effect.
The International Energy Agency projected in 2014 that under its "high
renewables" scenario, by 2050, solar photovoltaic and concentrated
solar power would contribute about 16 and 11 percent, respectively, of
the worldwide electricity consumption, and solar would be the world's
largest source of electricity.
Photovoltaic were initially solely used as a source of electricity for small
and medium-sized applications, from the calculator powered by a single
solar cell to remote homes powered by an off-grid rooftop PV system. As
the cost of solar electricity has fallen, the number of grid-connected solar
PV systems has grown into the millions and utility-scale solar power
stations with hundreds of megawatts are being built. Solar PV is rapidly
becoming an inexpensive, low-carbon technology to harness
renewable from the Sun.

APPLICATIONS
Several applications of wireless power transfer are apparent and
obvious. Firstly, WPT could eliminate traditional charging systems in
place today. Instead of plugging in a mobile phone or laptop via power
cord to charge the battery, wireless power can be harnessed and
implemented in a home such that a laptop and phone charge
continuously and wirelessly without the need for plugging anything in.
Higher level applications include charging of electric vehicles (EVs).
Electronic portable devices: Cell phones, laptops, tablets, even smart
watches are found all over the globe and are owned and used by billions
of people. What these devices all have in common is the need to
recharge their internal battery so that the device can be used while
mobile. Such is the paradox of portable devices: they provide
convenience by running off internal power so they can be used
anywhere, but always must return to be tethered to a power cord in
order to charge
Electric Vehicles: As concern over global warming and greenhouse gas
emissions grows across the globe, the prevalence of electric vehicles has
also increased. However, many envision that in the near future, one need
only park her car in a pre-determined spot in her driveway and the car
will charge wirelessly and automatically
Theoretical applications: Aerial Vehicles and Solar Power Satellites:
While portable device and vehicle charging are applications that could
be implemented in the near future, some other theoretical applications
have been posited for further research and development. One such
application is the Stationary High Altitude Relay Platform (SHARP)
