Effect of ferromagnetic and diamagnetic coil materials study on a wireless energy transfer system using mathematical model

Abstract

Wireless Power Transfer (WPT) technology is becoming widely used as a reliable and efficient way to transmit clean power. EVs are expected to replace gas-powered vehicles eventually due to the gradual depletion of fossil fuels. This WET method relies largely on Inductive Power Transfer (IPT). The receiver coil and transmitter coil are combined in this device. A magnetically coupled inductor is formed by these two coils. The transmitter coil generates alternating currents, which produce a magnetic field, which causes a voltage to be generated in the receiver coil. A major objective of this paper is to investigate the effect of ferromagnetic and diamagnetic materials on coil material for designing an optimum wireless energy transfer system. With the aid of coupled mode theory (CMT) mathematical model, two types of winding materials such as iron and copper, with different sizes, are evaluated and the results are validated using available experimental results. Feasibility study of ferromagnetic material with same design of diamagnetic materials are developed for the operating frequency ranges varies from 10 kHz, 20 kHz ,40 kHz , 60 kHz, 80 kHz, 100 kHz, 120 kHz, The Performance and electric and magnetic features of coupled coil of Wireless energy transfer system are evaluated based on Transmitter and receiver coil specification like Coil diameter, number of turns.,the inner and outer diameter of the coil, as well as the air gap (distance between coils). The main objective of this study is to improve power transfer efficiency with a minimal coil size and low material cost.
