This project work deals with wireless energy subject. Wireless power transfer or wireless energy transmission is the transmission of electrical power from a power source to a consuming device without using discrete manmade conductors. It is a generic term that refers to a number of different power transmission technologies that use time-varying electro-magnetic field. Wireless transmission is useful to power electrical devices in cases where interconnecting wires are inconvenient, hazardous, or are not possible. In wireless power transfer, a transmitter device connected to a power source, such as the mains power line, transmits power by electromagnetic fields across the space to one or more receiver devices, where it is converted back to electric power and utilized. In general, the efficiency of wireless power system will be very poor because of generating huge electro-magnetic field. To generate such a huge field, lot of current must be pumped in to the energy transmitting coil, where as power receiving coil may not receive all the energy that is induced in the power transmitting coil. Depending up on the distance between the two coils, some of its energy will be received by the secondary coil. If the secondary coil is kept very close to the primary coil, more than 70% energy can be captured by the secondary coil. As the distance is increased, accordingly power losses also will be increased. So here the wireless power transmission concept is designed to operate multiple devices individually. The devices connected here for demonstration purpose are mobile charging, LED light and a DC motor. As the concept is designed a proto type module, the wireless power is not sufficient to operate all the devices at a time. So the loads are demonstrated to operate one at a time individually. If there’s one bit of transformational technology in the mobile world today, it is wireless charging. Just as the world got a hang of using micro USB to charge everything and anything excluding Apple, the next best thing came along which is the wireless charging. Wireless energy works on the principle of electromagnetic induction. Coils of wire in the transmitter (coil) create a magnetic field as the current passes through. This field can induce an electrical current in an adjacent coil of wire without actually touching it. If this wire is part of a battery charging circuit, then you have wireless charging or it can be connected to any device to operate it directly.
