Abstract :
We have developed resonant coils for kW-class wireless power transfer systems used in industrial applications such as EV/PHEVs. The characteristics requested for such coils are small size, lightweight and low loss. In this study we have simulated two test coils that have different arrangement of ferrite cores. Both coils have outline size of 50 cm square and thickness of about 3 cm. The proposed core arrangement reduced the core loss by 38% compared with the conventional type.
