Wireless power transfer (WPT) technology has attracted considerable attention in recent years, and there have been numerous reports about this technology. This has led to ambiguity over the actual state of WPT technology for electrical vehicles (EV) in Japan. Therefore, this paper describes the WPT technology using the kilohertz band for EVs available in Japan. WPT requirement for EV, circuit topology, coil types, control method, component, foreign object detection, and dynamic charging in Japan are summarized in this study. Power transmission distance Power transmissiondistance [21] is defined as the distance between the power transmission side coil and the ground surface. Since the minimum ground clearance varies depending on whether the vehicle is a passenger car or an SUV, the power transmission distance is set separately between 100 and 250 mm in three zones. Transmission power Transmission power [21] isdefined as an AC input power of 3.7, 7.7, and 22 kW assuming a passenger car, medium vehicles, and large vehicles, respectively.

In this study, a modified single-switch bridgeless power factor correction (PFC) single-ended primary-inductor converter (SEPIC) structure is proposed. The major practical drawbacks of the existing structure are the presence of circulating current and high maximum current stress at the input capacitor and line diodes. Therefore, to overcome these problems, the existing structure is restructured by repositioning the line diodes in series with input inductors. Besides, the principle of design parameters optimisation is used based on the balancing energy compensation between input capacitors and output inductor. This structure is designed to operate in discontinuous conduction mode in order to achieve almost a unity power factor. The operation principle and design consideration of the modified structure is introduced in details. The experimental results demonstrate that the total harmonic distortion current is reduced from 56.3 to 4.9% after the optimisation process is performed, and at the same time the dead zones are inherently eliminated. Furthermore, it is shown that the output voltage ripple frequency is always double from the input line frequency of 50 Hz and the output voltage ripple is constantly lower than the maximum input voltage ripple. Thus, the designed parameters of the experimental converter are verified with ∼160 W of the converter output power.

This paper discusses the current total harmonic distortion (THDi) and voltage ripple minimization of SEPIC converter based on parameters design optimization. This conventional PFC SEPIC converter is designed to operate in discontinuous conduction mode in order to achieve almost unity power factor. The passive components, i.e., inductor and capacitor are designed based on switching frequency and resonant frequency. Meanwhile, the ranges of duty cycle for buck and boost operations are between 0
