Wireless power transfer - Wikipedia


October 28, by Marie Christiano Wireless Power Transfer holds the promise of freeing us from the tyranny of power cords. This technology is being incorporated into all kinds of devices and systems. Let's take a look! Wireless power transmission applications pdf Wired Way The majority of today's residences and commercial buildings are powered by alternating current AC from the power grid.

Electrical stations generate AC electricity that is delivered to homes and businesses via high-voltage transmission lines and step-down transformers. Electricity enters at the breaker box, and then electrical wiring delivers current to the AC equipment and devices that we use every day—lights, kitchen appliances, chargers, and so forth.

All components are standardized and in agreement with the electrical code, wireless power transmission applications pdf. Any device rated for standard current and voltage will work in any of the millions of outlets throughout the country. While standards differ between countries and continents, within a given electrical system, any appropriately rated device will work. Wireless Power Transfer WPT makes it possible to supply power through an air gap, without the need for wireless power transmission applications pdf wires.

WPT can provide power from an AC source to compatible batteries or devices without physical connectors or wires, wireless power transmission applications pdf. WPT can recharge mobile phones and tablets, drones, cars, even transportation equipment.

It may even be possible to wirelessly transmit power gathered by solar-panel arrays in space. WPT has been an exciting development in consumer electronics, replacing wired chargers. The concept of transferring power without wires, however, has been around since the late s. Three light bulbs placed 60 feet 18m from the power source were lit, and the demonstration was documented.

Tesla had big plans and hoped that his Long Wireless power transmission applications pdf Wardenclyffe Tower would transmit electrical energy wirelessly across the Atlantic Ocean. That never happened owing to various difficulties, including funding and timing. WPT uses fields created by charged particles to carry energy between transmitters and receivers over an air gap.

The air gap is bridged by converting the energy into a form that can travel through the air. Depending on the power and distance, energy can be effectively transferred via an electric field, a magnetic field, or electromagnetic EM waves such as radio waves, microwaves, or even light.

While some of the companies promising WPT are still working to deliver products, Qi pronounced "chee" charging is standardized, and devices are currently available.

The standard supports both inductive and resonant charging technologies. Inductive charging has the energy passing between a transmitter and receiver coil at close range.

The presence of a Qi logo means the device is registered and certified by the Wireless Power Consortium. When first introduced, Qi charging was low power, wireless power transmission applications pdf, about 5W. The first smartphones using Qi charging were introduced in InQi was expanded to include 15W, which allows for quick charging.

Only devices listed in the Qi Registration Database are guaranteed to provide Qi compatibility. There are currently over products listed, wireless power transmission applications pdf. It is important to recognize that products with the Qi logo have been tested and certified; the magnetic fields they use will not cause problems for sensitive devices such as mobile phones or electronic passports.

Registered devices are guaranteed to work with all registered chargers. WPT for consumer devices is an emerging technology, but the underlying principles and components are not new. Maxwell's Equations still rule wherever electricity and magnetism are involved, and transmitters send energy to receivers just as in other forms of wireless communication. WPT is different, though, in that the primary goal is transferring the energy itself, rather than information encoded in the energy.

Exposure to electromagnetic radiation can be a concern, and there is also the possibility that the fields generated by WPT transmitters could interfere with wearable or implanted medical devices.

The actual conversion circuitry will depend on the technology used. In addition to the actual transfer of energy, the WPT system must allow the transmitter and receiver to communicate.

This ensures that a receiver can notify the charging device when a battery is fully charged. The concept of near-field vs. Transmission techniques, wireless power transmission applications pdf, the amount of power that can be transferred, and proximity requirements are influenced by whether the system is utilizing near-field or far-field radiation. Locations for which the distance from the antenna is much less than one wavelength are in the near field, wireless power transmission applications pdf.

The energy in the near field is nonradiative, and the oscillating magnetic and electric fields are independent of each other. Capacitive electric and inductive magnetic coupling can be used to transfer power to a receiver located in the transmitter's near field. Locations for which the distance from the antenna is greater than approximately two wavelengths are in the far field. A transition region exists between the near field and far field. Energy in the far field is in the form of typical electromagnetic radiation.

Far-field power transfer is also referred to as power beaming. Examples of far-field transfer are systems that use high-power lasers or microwave radiation to transfer energy over long distances.

In addition to the idea of walking into a room equipped for WPT and having your devices charge automatically, much more ambitious projects are in place. Using Qi charging, of course! This wireless technology is convenient, to be sure, but it may also charge cars faster than plug-in charging can.

An experimental system for wirelessly powering drones has already been demonstrated. And as mentioned above, ongoing research and development is focused on the prospect of supplying some of Earth's energy needs using WPT in conjunction with space-based solar panels.

While Tesla's dream of having power delivered wirelessly for everyone's use is still far from feasible, many devices and systems are using some form of wireless power transfer right now. From toothbrushes to mobile phones, from cars to public transportation, there are many applications for wireless power transfer.

The Capital Cost for practical implementation of WPT seems to be very high and the other disadvantage of the concept is interference of microwave with present communication systems. Long distance charging ,High current and voltage charging are not support very fast charging not supported. I think high electro-magnetic fiend disturb charging.

But it has several advantages, any device that support wireless charging can accept charge from other device charger ie.

And high risk of Skin diseases wireless power transmission applications pdf human who repeated expose to the high dose of microwave radiation and slight neural issues.
