Abstract
The last couple decades ushered in the development of mobile devices, so the interest in wireless energy has grown very rapidly. It is important to mention that the electrical-wire grid has spread to almost every corner of the world, so now wireless transfer for distances of even several tens of centimeters could be useful. Wireless Power Transmission is the process that takes place in any system where electrical energy is transmitted from a power source to an electrical load without interconnecting wires. we want use WPT. Due to the some reasons, low efficiency of wired transmission lines, high mechanical cost of conductors and poles, high cost of insulators, high cost of grid stations, high cost of repair and maintenance, health hazardous, requires large area for poles, difficult to install in hilly areas. We use the NEAR FIELD Method in which we apply the RESONANT INDUCTION. In resonant coupling, if inductors are tuned at a mutual frequency, significant power may be transmitted over a range of many meters. There are some benefits of WPT which are, high efficiency, low installation cost, low repair and maintenance cost, no corona effect, reduce cost of protection. If the primary and secondary coils are resonant at a common frequency, it turns out that significant power may be transmitted between the coils over a range of a few times the coil diameters at reasonable efficiency. Resonant Inductive coupling is also used for wireless charging of electronic devices such as electric tooth brushes, laptops ,mobile phones and charging mats such as splash power.
