N2 - The dynamic wireless charging system was recently been introduced as a replacement for the cord charging system. However, the misalignment issue in dynamic wireless power transfer (DWPT) leads to a reduction in efficiency and a deterioration in transmission power stability. Moreover, the transmitted power also pulsating in the actual implementation of a grounded mobile vehicle due to the dynamic behavior of the receiver. Since most of the studies focused only on horizontal misalignment, the system could only operate in a certain speed. To address the issues, this paper proposes a rotational dynamic wireless charging system where the transient response in speed of a motor (dynamic current load) is also considered with the continuously moving platform. Additionally, the structure of DD (bipolar coil) and Q (unipolar coil) shapes in the transmitter side and DDQ (bipolar and unipolar coil connected in series) shape in the receiver side are utilized. At the same instant, LCC compensation is also adopted in multi-transmitter for cost-down purposes. The presented analysis of the circular railway-based wireless charging system is validated with simulation for both magnetostatic and dynamic terms.
