The studies on Wireless Power Transfer (WPT) technology and peripherals in Electric Vehicle (EV) applications are intensifying. While the energy received from the WPT system is transferred to the EV battery, the direct current (dc)/dc converter circuits are used. The dc/dc buck converter topologies are one of them. The converter circuits must be highly efficient, lightweight, and compact to have a high range in EV vehicles. There are asynchronous buck, synchronous buck, and interleaved synchronous buck converter circuit topologies from the literature. In this study, the efficiency results of these circuit topologies were analyzed using MATLAB/Simulink and experimental studies. This study contributes to the literature by conducting circuit-level efficiency analysis and component-level power loss analysis. It has been observed that the interleaved synchronous buck converter circuit operates at 99% efficiency at 1066 W. In addition, it has been shared with the oscilloscope results that the current ripples of this circuit topology are lower than other circuit converters. Specifically, there has been a significant reduction of 56% in power losses, particularly in the interleaved synchronous buck converter (ISBC). This study analyzes the dynamic behavior of the dc/dc buck converter topologies, and results about their performance are given.

This paper proposes a novel reflexive tuning dynamic inductive power transfer (DIPT) system with a single inverter connected to multiple transmitter coils, which makes DIPT systems simpler and more cost-effective. Traditional DIPT systems have an individual inverter per transmitter coil, leading to considerable costs when transmitter coils span long distances on roads. The proposed reflexive tuning DIPT system leverages a reflected reactance from a receiver coil to allow a single inverter to drive multiple transmitter coils. Using reflexive tuning, the approach naturally achieves high currents solely on the transmitter coil coupled with a receiver coil when a vehicle moves along a DIPT roadway. Simultaneously, the other uncoupled transmitter coils connected to the shared inverter operate at notably reduced currents. Theoretical analysis, design, simulation, and experimental results are provided for the proposed reflexive tuning circuits. Simulation results indicate that the proposed reflexive tuning circuit can reduce the uncoupled transmitter current by 37% compared to the conventional double-sided LCC tuning circuit while maintaining the output power at the same level. Experimental results with a 50 kW prototype demonstrate operation on both automated rail and vehicle systems. The results demonstrate dc-dc efficiency of 90% per a single transmitter coil configuration with 223 mm air gap and capability of power delivery at least up to 60 km/h speed.
