Abstract
In this research, a wireless charging system for electric vehicles (EVs), based on the principle of magnetic resonance coupling (MRC), is characterized by high transmission capacity and good operating efficiency, especially when the operating voltage is raised. A system was designed that achieves stable and effective performance at high operating voltages, which contributes to reducing size and cost without sacrificing efficiency. A mathematical model was built to achieve this within the simulation environment. The model included the representation of the transmitting and receiving coils, their electrical information, self-inductance, resistance, and the coupling coefficient between the two coils. The effect of the operating voltage, the separation distance between the two coils, and the outer diameters of the coils on the efficiency of energy transfer and the transmitted power was also analyzed. The results showed a noticeable improvement in the transmitted power, reaching 14.24 KW, which is a relatively large capacity, with an efficiency reaching 84.61% at high voltages at a transmission coil diameter of 400 mm.
