Wireless power transmission (WPT) is a technology that enables the transmission of electricity between two points with no physical connection. It is a rapidly developing area of research with numerous potential applications, from powering small electronic devices over short distances to providing electricity to remote locations. This article will examine the application field and working principle of WPT.

WPT technology has numerous potential applications. The ability to transfer energy between two points without the need for a physical connection eliminates the need for bulky and expensive cabling systems. It can be used in situations where other forms of energy transmission technology cannot be used, such as in hazardous or confined environments. WPT technology can also be used to transmit electricity over long distances, eliminating the need for costly and inefficient distribution networks. It can also be used to transmit power to remote locations, providing energy to regions currently without access to electricity.

The working principle of WPT technology is based on a well-known phenomenon in electrical engineering known as magnetic induction. In a magnetic induction based WPT system, the transmitter and receiver, which are connected wirelessly, each contain coils of wire. When an alternating current is passed through the transmitter coil, an electromagnetic field is created. This field couples with the receiver coil to induce a voltage. This induced voltage is rectified into an alternating current which can then be used as an electrical power source.

In the past, WPT technology has been limited to short-range applications, due to the large losses that occur at longer distances. However, modern advances in antenna design and amplifier technology have enabled WPT systems to be used over longer distances, making them a viable option for a wide range of applications. In addition, new technologies such as rectenna and rectifying antenna systems promise to further increase the efficiency of WPT systems.

WPT technology is quickly becoming an integral part of the power grid, allowing for more efficient power distribution and opening up new opportunities for renewable energy sources. WPT is used in numerous applications, from home and office applications to industrial sites and medical equipment.

In summary, WPT technology is a rapidly developing area of research with numerous potential applications. It works on the principle of magnetic induction, whereby an alternating current passing through the transmitter coil induces a voltage in the receiver coil. Modern advances in antenna design and amplifier technology have enabled WPT systems to be used over longer distances, making them a viable option for a wide range of applications. WPT technology is quickly becoming an integral part of the power grid, allowing for more efficient power distribution and opening up new opportunities for renewable energy sources.
