ABSTRACT The design and development of a wireless power transfer (WPT) system that does not require wires or plugs for electric vehicle (EV) charging is presented in this study.The proposed system utilizes magnetic resonance coupling technology to transfer power between a transmitter coil embedded in the ground and a receiver coil integrated into the EV. The system operates at a frequency of 85 kHz and can deliver up to 3.7 kW of power with an efficiency of 90%. The WPT system consists of a transmitter unit, a receiver unit, and a control unit. The transmitter unit comprises a high-frequency inverter, a transmitter coil, and a compensation network. The receiver unit consists of a receiver coil, a rectifier, and a DC-DC converter. The control unit ensures efficient power transfer and safety features. Experimental results demonstrate the system's feasibility and efficiency, paving the way for convenient and automated EV charging.
