A Study on Contactless Energy Transfer

One of the latest developments to draw the interest of all engineers is “Contactless Energy Transfer” for powering & controlling motors.It is the transmission of electrical energy from a Power Source to an Electrical Load without using conductors. The “Wireless Power Transmission” differs from that of wireless signal transmission such as radio and mobile telecommunication.The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods under consideration include electromagnetic radiation in the form of microwaves or lasers.
