WIRELESS POWER TRANSFER
Future Backbone of Smart City Model Introduction It is possible to transfer electricity without the use of cables using Wireless Power Transfer (WPT) . It is possible to power compatible batteries and devices using conventional AC power without the use of any physical connectors thanks to WPT, which utilises technologies based on electric, magnetic, or electromagnetic fields. In this method, charged particles form an electromagnetic field, which is then used to convey energy over an air gap, where it is then converted by the receiver into a useful household current. When two things with a similar resonant frequency exchange energy, the off-resonant items lose just a little amount of energy in the process. Wireless power transfer (WPT), or the transfer of electrical energy from a power source to an electrical load without the use of connecting wires, is particularly useful in the wireless functioning or recharging of various products, such as smartphones, tablets, and lapt...
