Wireless power transfer system

This project has demonstrated that 10 kW of power can be transferred between a pair of coils, spaced 70 mm apart by air. These coils are individually wrapped around an H-shaped ferrite core, compensated by the primary-series, secondary-parallel topology to achieve resonance, thereby improving the ef...
