Wireless Power Transfer - ( Introduction & History) Part 1 by Valuates Reports

Wireless power transfer or wireless power transmission (WPT) is the transmission of electrical energy from source of power (sender) to destination (receiver) or electrical device without using any wires or cords. It is extremely useful in cases where the use of wires becomes risky or inconvenient, and where the delivery of energy needs to be continuous. In such cases, power is transmitted through magnetic induction, magnetic resonance, radio frequency, lasers, microwaves, etc



It is not a new concept. Rather, it has been present for a long time and has been in application for satellite communications, Radio Frequency Identification tags, etc. Although these applications transfer power in smaller amounts, within Microwatts to Milliwatts, wireless power transfer is also being used in industries and other high-power applications. Fundamentally, the method of wireless power transfer uses the basic concept of Faraday’s law of induction, which states that a changing magnetic field causes an alternating current (AC). This method consists of the use of two coils: a transmitter or primary coil, and a receiver or secondary coil. Both of these coils act like inductors, or transformers without any cores, basically making them two air coils which are inductively coupled.


OVERVIEW & HISTORY


Wireless power transfer is a general term for technologies that transmit energy using electromagnetic fields. These technologies are systems that consist of a transmitter or primary device which is connected to a source of power, and the receiver device, which receives the power and converts it into currents. The system of wireless power transfer reduces the existing transmission cables, towers and substations of high-tension power between the generating stations and the end-consumers. This system was also made to essentially lower the costs of distribution and transmissions, thereby reducing the end cost of electrical energy for the consumers. Wireless power transfer was established so that power could be transmitted to places where wired transfers of energy was not possible.



In 1865, when Maxwell published his Theory of Electromagnetism, he stated that electromagnetic waves move at the speed of light, and then concluded that light itself was one such wave like that. In the 1890s, Nikola Tesla also experimented in the field of wireless power and energy transfers and transmitted power by inductive and capacitive coupling, using radio frequency-based transformers, which are now famously known as Tesla Coils. These coils measured 16 meters in diameter and were known to transmit high voltage currents without any wires. These were also patented and were used for generating high frequency alternating currents. He was one of the first pioneers of this technology.



In 1904, Nikola Tesla designed and constructed the Wardenclyffe Tower, which was used mainly for the wireless transfer of electrical power. Nikola Tesla’s system was one of the very first systems which could transmit electricity without wires. He used a radio frequency resonant transformer of the famous Tesla coils between 1891 and 1898 to transmit electrical energy. This could produce high voltages as well as high frequency alternating currents. This way, he could also transfer power and energy over short distances without any wire connections. 1893, Tesla also demonstrated the illumination of around 200 vacuum bulbs by means of a resonant circuit without using wires for power transmission at the World Columbian Exposition in Chicago. The receiver worked on the same principle like that of radio receivers where the device was supposed to be in the transmitter. In the 1900s, when Nikola Tesla started working on the Wardenclyffe Tower, he demonstrated a prototype of small-scale wireless power transfer for a “World Wireless System” that could broadcast information as well as power around the world. Tesla’s ideas and experiments failed a lot of times, he still stated that the experiments were successful, although he had no proof that these experiments were ever able to transmit power beyond the short-range distances.



Later, in 1995, Professor Grant Covic and Professor John Boys of the University of Auckland developed systems which could transfer large amounts of energy and power across small air gaps. Then, in 2011, in order to develop and improve the resonator performances, Fei Zhang made due use of strongly coupled electromagnetic resonator technologies to transmit energy over a longer field distance. Currently, in recent years, wireless power transfer has spread its uses around the world in many areas. The biggest example of this is the production of power by placing different satellites with different solar arrangements in Earth’s orbit, and then transmitting this power in the form of microwaves back to the earth. Not only that, with an advancement in technology, wireless power transfer has also helped in the development of fuel-free-electric vehicles, robots, electronic appliances, mobile phones etc.
