Analysis and Design of a Two-winding Wireless Power Transfer System With Higher System Efficiency and Maximum Load Power

Maximum load power and higher efficiency of the system are two major design aspects of the wireless power transfer system. This article analyses the concepts employed to assess the maximum load power along with high system efficiency under varying coil separation, and various working frequencies with dynamic load conditions through a conventional two-winding WPT system. Besides developing analytical links between load power and system performance, a developer can select an optimum design for the enhancement of the WPT system. A demonstration of the circuit model has been built in MATLAB/SIMULINK to examine the efficiency of the system and load power. The obtained data are shown to be in close agreement with the relevant theoretical principles and offer results for the simulation prototype based on the various functioning criteria mentioned above.
