Abstract
Several papers have examined the power requirements for Dynamic Wireless Power Transfer (DWPT), but none have compared all types of vehicles and designed appropriate coils. In this paper, a new quasi-optimal load was adopted to make the SS circuit more usable, and in optimizing the transmission coil, the economically best one was adopted considering the average efficiency and the coil installation rate. Although a trade-off between the average transmission efficiency and the coil installation rate was shown, the reduction in the number of coils installed with the coil installation rate was shown to be very dominant compared to the efficiency. As a result, it was found that with more economical coils, a 25-ton truck could be driven 800 km, and a light-duty vehicle could be driven without considering its range.
