This paper proposes a method for stable power transmission in dynamic wireless power transfer (DWPT) systems with a coil array installed on the ground. The proposed method adopts a Circular-Solenoid type multi-coil on the electric vehicle (EV) side to utilize both vertical and horizontal magnetic fields, achieving stable power transmission all over the DWPT lane. In the experiments, a prototype was constructed, and the magnetic coupling characteristics of the ground and EV side coils were clarified. The power transmission characteristics were then derived, and a guideline was provided for efficiently and stably transmitting 3 kW of power to EVs all over the DWPT lane.
