Abstract:
Wireless Inductively Coupled power transfer is a new technology to transfer electrical power without any physical contact( wires) between the source and the load. The basic aim of this project is to propose the use of a simple, cheap and easiest technique for charging any electrical device. The various technologies that are available so far in market for wireless transmission of electricity and the need for a wireless system of energy transmission are to be discussed here. The main problem behind this is that how to transfer power wirelessly through inductively load without any bad effect on enviromnent .The core of this technology is making use of the magnetic resonance concept for transmitting the power wirelessly for charging any electrical device.. An impedance matching network is to be used for achieving maximum power transferred. The practical results are very close to the result that are obtained using the mathematical model and the theoretical calculations.Inductively wireless power transfer (IWPT) is being discuss into as a future solution for charging the electric vehicles and many other electronic devices.In our case the coil coupling is the critical issue in IWPT as the transmitting coil (TC) is buried under the ground and receiving coil (RC) is on to the exact location to the chassis of vehicle,devices and other electronic components. COMSOL Multiphysics Finite element analysis (FEA) is used to determine and comment on the inductive parameters to find the best RLC values. It also includes the discussion on parametric types like inner diameter, coil gap distance, different number of turns on transmitter side and receiving side coils. The outcomes are then to compare and select the best coil structure for charging the electric vehicle and many other electronic devices.
