“…The Single-phase Single-stage topologies [97]- [102] employed for WPT are discussed here. The single-phase topologies are the most widely utilized form of conversion since the utility grid consists of the AC supply which should be transformed to high-frequency AC and transmitted wirelessly then rectified into DC for the EV.…”

Wireless Power Transfer (WPT) particularly in the field of Electric Vehicle charging applications has wide research opportunities because of its huge growth. The power transfer efficiency is of major concern and researchers are finding ways to improve it by reducing stages of the WPT and making it better than the wired EV charging method. The increasing penetration of charging stations in the grid brings many challenges and hence to find a suitable control scheme to enhance input power quality. For the most optimal operation and comprehensive support, the charging systems must incorporate a suitable converter topology, a well-defined control strategy, and comply with all relevant grid codes and standards. For smooth and efficient functioning these features must be included in the EV charging systems. This paper presents a review of single-stage topologies and the power factor correction methods employed for EV wireless charging. An overview of different charging methods is first presented then the AC input and DC input singlestage converter are discussed, and following that methodologies for improving power factor correction are reviewed with the comparative analysis from different literatures. Finally, the challenges in single-stage wireless power transfer (SSWPT) were addressed and the future scopes were discussed which provides the future research directions.

“…Until now, there have been three ways to obtain CC and CV outputs in the existing research. First, CC and CV outputs can be achieved by applying variable inductors [10,11] or designing a compensation topology [12][13][14]. However, variable inductors or additional power switches and auxiliary capacitors are employed in these methods, which will lead to a reduction in overall efficiency and affect the lightweight nature of the system.…”

In this paper, an autonomous wireless power transfer (WPT) system with constant voltage output in a wide load range is presented. Here, combining self-oscillating control and phase-shift control, a new implementation of the autonomous WPT system is proposed. The proposed autonomous WPT system operates using a self-oscillating control method in the strong coupling region, which can automatically maintain the constant output voltage. In the weak coupling region, a phase-shift control method with a fixed frequency and a variable duty cycle is implemented, and a control strategy based on output voltage estimation is proposed to obtain the constant output voltage. In addition, according to the operating frequency characteristic of the proposed autonomous WPT system, a corresponding coupling region judgment method is presented to guarantee the realization of switching between the two control methods. An experimental prototype with a 24 V output voltage is constructed to validate the practicability of the proposed method. The experimental results show the proposed autonomous WPT system can obtain constant output voltage in a wide load range.
