4. INTRODUCTION
• Welcome everyone to this exciting presentation on wireless
power transmission. Today, we will explore a technology that
has the potential to revolutionize the way we use and think
about electricity. Imagine a world where you can charge your
phone or electric car without ever plugging it in. A world where
medical devices can be powered wirelessly, eliminating the
need for invasive procedures. This is the future that wireless
power transmission promises to bring.
• But how does it work? What are its benefits and limitations?
And what does the future hold? These are some of the
questions that we will answer in the following slides. So sit
back, relax, and let's embark on a journey into the world of
wireless power transmission.

5. How it Works?
➢ Wireless power transmission is a revolutionary
technology that allows electrical energy to be
transferred from one place to another without the
need for wires or cables. Instead, it uses
electromagnetic waves to transmit power through
the air. This is made possible by a transmitter and
receiver that are tuned to the same frequency,
allowing them to exchange energy wirelessly.
➢Compared to traditional wired power
transmission, which relies on cables and wires to
transfer electricity, wireless power transmission
offers several advantages. For example, it
eliminates the need for bulky cords and charging
stations, making it more convenient and less
cluttered. It also reduces the risk of electrical
shocks and fires, as there are no exposed wires to
touch or damage.

6. Types Wireless Power Transmission
a) Resonant Wireless Power
Transmission:-Uses resonant circuits to
transfer power wirelessly, allowing for
greater distance between the
transmitter and receiver.
b) Non-Resonant Wireless Power
Transmission:-Uses electromagnetic
fields to transfer power wirelessly, but
is limited in distance and efficiency.

7. Applications
• Wireless power transmission has numerous applications
across a wide range of industries. One of the most significant
is in the field of smartphones. With wireless charging
capabilities, users can simply place their phone on a charging
pad and have it charge without having to deal with the hassle
of cords and cables.
• Another area where wireless power transmission is being
utilized is in electric vehicles. By using wireless charging pads
installed in parking spots or garages, electric vehicles can be
charged without requiring any physical connection. This not
only provides convenience for the user, but also helps reduce
the number of charging stations needed.
• In the medical industry, wireless power transmission is being
used to power implantable medical devices, such as
pacemakers. This eliminates the need for invasive surgeries to
replace batteries and allows patients to live a more normal life
without worrying about their device running out of power.
• These are just a few examples of the many applications of
wireless power transmission that are currently being explored
and developed.

8. Benefits of Wireless Power Transmission
Methods
• Wireless power transmission offers numerous benefits over
traditional wired power transmission. One major advantage is
increased convenience. With wireless charging, there's no need to
fumble with cords or search for outlets. Simply place your device
on a charging pad and let it power up. This is especially useful for
busy professionals who are always on the go.
• Another benefit of wireless power transmission is reduced clutter.
Traditional power cords can create a mess of tangled wires and
take up valuable desk space. Wireless charging eliminates this
problem and creates a cleaner, more organized workspace.
Additionally, wireless charging reduces the risk of tripping hazards,
making it a safer option for homes and offices alike
• Increased Convenience:-Wireless power transmission methods
eliminate the need for cords and cables, making it easier to charge
devices without having to worry about finding an outlet or
untangling cords.
• Reduced Clutter:-Without the need for cords and cables, wireless
power transmission methods can reduce clutter and make spaces
look tidier. This is especially beneficial in public spaces like coffee
shops or airports.

9. Challenges of Wireless Power Transmission
Methods
• While wireless power transmission has great potential, it is not
without its challenges. One major challenge is range. Currently,
wireless power transmission is limited in terms of how far it can
transmit power. This makes it difficult to use in larger spaces or
for applications that require power to be transmitted over long
distances.
• Another challenge is efficiency. Wireless power transmission is
not yet as efficient as traditional wired power transmission. This
means that more energy is lost during transmission, which can
make it less attractive for certain applications.
• Efficiency: Wireless power transmission is less efficient than
wired transmission, resulting in energy loss and reduced
charging speed.
• Compatibility: Different devices may require different wireless
power transmission technologies, making it difficult to create a
universal standard.
• Cost: Implementing wireless power transmission technology can
be expensive, especially for large-scale applications like electric
vehicle charging stations.

10. Future Outlook of Wireless Power Transmission
Methods
• As we look to the future of wireless power
transmission, we can expect to see significant
advancements in technology that will make it even
more efficient and effective. Researchers are already
exploring new ways to increase range and reduce
energy loss, which could lead to widespread
adoption of this technology in a variety of industries.
• In addition to these technical advancements, there
are also many exciting potential applications for
wireless power transmission. For example, imagine a
world where electric vehicles can charge wirelessly
while driving on the highway, or medical devices that
can be powered without the need for bulky
batteries. These possibilities may seem like science
fiction, but they are becoming increasingly feasible
with each passing day.
