N2 - There have been various types of transmitter coils proposed for dynamic wireless power transfer. This study compared three types of coils: circular (spiral) coil, DD coil, and 85 kHz self-resonant coil. The coil performance was evaluated under an ideal environment on the ground side and after coil embedment in the road, and the characteristics of each coil were clarified. In this study, the allowable current value of the litz wire was evaluated as a constraint condition. The results of the verification using actual coils showed that when the input voltage was increased to around the allowable current value of the litz wire, the 85 kHz self-resonant coil obtained approximately 30 kW of power at the input voltage conversion value of 1160 V. The output power was approximately 8 kW higher than that of the circular coil and the DD coil. It was also found that the circular coil and DD coil showed almost similar power feeding performance when compared.
