N2 - In Dynamic wireless power transfer, it is essential to detect vehicles and perform switching control of the transmission coils because applying power to the transmission coils when no vehicle is present causes standby losses. Existing systems for vehicle detection and switching control of the transmission coils in DWPT systems cannot handle multiple vehicles. In this paper, we propose an N-Legged-Converter system that can handle multiple vehicles by controlling the voltage of each transmission coil individually according to the presence or absence of vehicles by phase shifting, thereby reducing losses during standby. As a result, vehicle detection was achieved without additional sensors, reducing standby losses by 99% in simulations and 96% in experiments.
