Abstract: Now-a-days, wireless transfer of electric power has received much attention in the world arena. As a safe, reliable and convenient technology, Magnetic resonance coupling (MRC) based wireless power transfer (WPT) system shows a remarkable ability to power up in a wide range from mW to kW range. In this paper conventional magnetic field analysis with maximum power transfer theorem has been used to explain the frequency characteristics of the transferred load power. The intensity of magnetic field, induced receiver voltage, physical air gap of coils relating to the dimension of the coils has been examined. The experimental results are well agreed with the theoretical results. The acquired analysis depicts the optimal physical separation condition relating to the size of the charging coils of a WPT system.
Keywords: Magnetic circuit model; Optimal separation condition; WPT system.
