Design of a wireless charging system used in light-duty electrified automobiles

This study proposes a design and development of Series-Series Compensated topology based (SSC) wireless power transfer system to charge the battery in light-duty electrified automobiles, e.g., electric scooters. An asymmetric resonant methodology is adopted by adjusting the secondary-side resonant capacitance to make the system resonate only at the secondary side, which is different from the prevalent symmetric resonant topology. The experimental data at 250W test matches the simulation result well, which improves the system efficiency.
