Custom 40W WPT system efficiency. power transmission Power transmission is the movement of energy from its place of generation to a location where it is applied to performing useful work. A large part of the energy sent out by the generating plant must arrive at the receiver or receivers to make the system economical. Wireless power can be defined as the transmission of electrical energy from a power source to an electrical load without connecting wires. The goal of the project was to develop a Wireless Power Transfer (WPT) System and implement wireless power transmission. The experimental results confirm that the PDL is enhanced from 1.93 W to 2.5 W by employing the proposed technique rather than a single-coil system. The proposed system consists of three inductive links each one tuned at a harmonic of the operating frequency. The next essential phase includes WPT in order to keep up with the fast growing industry. The concept of Wireless Power Transmission System is explained with functional block diagram shown in Figure 2. Free space wave impedance. The charging flux is totally localized within the covered area between the selected primary winding and the secondary winding inside the load. Wireless power transfer involves the transmission of power from a power source to an electrical load without connectors, across an air gap. The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. The concept of wireless power transmission has been around since the mid 17 th century. It is reliable, efficient, fast, low maintenance cost, and it can be used for short range or long range.
