Dynamic Wireless Electric Vehicle Charging with Seamless LCC-S Pad Handover Control

The demand for efficient and user-friendly charging infrastructure has led to the growth of electric vehicles. Wireless power transfer technology offers a compelling alternative; however, existing dynamic wireless power transfer implementations often rely on complex vehicle positioning systems, inter-pad communication protocols, and real-time adaptive control algorithms, all of which contribute to system complexity and reduced reliability. This paper presents a simplified dynamic wireless charging architecture design for vehicles in motion, employing LCC-S compensation topology. In the proposed system, the transmitter pads are sequentially activated in a defined time domain frame and they are characterized with distinct mutual inductance values. A front-end AC-DC converter rectifies a 230V RMS supply to a 325V DC, which is subsequently elevated to 600V DC through a boost converter incorporating power factor correction. The LCC-S network with high-frequency inverter operating at 85-92 kHz is tuned to resonance so as to suppress reactive power. The simulation result confirms stable output characteristics, with the battery terminal voltage of 60V and an average current of 10A sustained throughout the pad transition intervals. The proposed system maintains an uninterrupted power supply without detectable discontinuity during pad handover events.
