Analysis, Experimental Results, and Range Adaptation of Magnetically Coupled Resonators for Wireless Power Transfer
Carbon emission minimization is one of big challenge in this century. For this purpose, in public transport point of view, the integration of electric vehicle is growing fast. Now the intention of this work is to design wireless charger with the aim of charging vehicle battery. The charger contains with a transmitter antenna which is assembled in parking garage surface in a particular area and a receiver antenna which is attached with vehicle bottom side with battery is to be charged. Here inductive power transfer technique is applied to transfer energy from transmitter to receiver through the air-gap in an optimum distance for achieving high efficiency of transfer link. MATLAB/SIMULINK is used to simulate the power pad of transmitter and receiver with proper calculation of inductance in each pad and mutual inductance between pads. The high frequency signal is thrown for traveling through the air-gap due to contain high signal strength. The received signal is further rectified to DC for restoring it into battery. This paper focuses the design of transmitter and receiver with proper investigation of circuit parameter of transmitter antenna and receiver antenna for electric vehicle. Finally the charger efficiency is determined with MATLAB/SIMULINK.
