In this paper wireless charging using a resonant auxiliary winding is evaluated, showing that a substantial increase of the power level is possible with the extra winding. The coils have been evaluated theoretically and by means of FEM-analysis. Further on verification has been done on a laboratory 6 kW-charger. The charger has been used for charging the battery of a small test vehicle.
