“…Consequently, this configuration proves unsuitable for deploying on the secondary side, which lacks complex high-order control schemes. A dual buck-boost converter, employing a novel asynchronous control based approach, is proposed in [111], in which this innovative control method facilitates independent modulation of the control signals for the primary switches, leading to a reduction in output ripples and fluctuations. Additionally, this technique effectively mitigates the stress experienced by the inductor current and switch current, resulting in a notable reduction in converter losses.…”

Dynamic wireless charging systems (DWCS) for electric vehicles is an effective solution to overcome driving range anxiety, high volume, and cost of battery by offering continuous charging for electric vehicles in motion. However, this technology suffers from some challenges associated with the high cost of infrastructure and power pulsation at the battery side, hindering the widescale commercial adoption of the technology. As the electric vehicle moves along the transmitter coils, power pulsation arises due to fluctuation in the mutual coupling, which deteriorates the battery's lifetime and the overall system's efficiency. In recent years, a significant volume of research methodologies have been proposed to address power fluctuation in DWCS. These methods can be categorized into three main areas, which include developing magnetic coil structures to suppress the coupling variation, optimizing the compensation network for coping with the coupling fluctuation, and applying controllers for output power stabilization. This paper presents a comprehensive review of the current literature on magnetic coil structures, compensation network topologies, and control schemes aiming to address the impacts of power variation in DWCS. This paper gives a new and holistic insight into the challenges and the corresponding solutions to address the power pulsation issues in DWCS.

“…A number of control schemes have been proposed to achieve the load-independent CC and/or CV output and misalignment tolerance, such as additional DC-DC converter [118][119][120], frequency tuning [52,121], maximum frequency tracking [122], phase shift control [123][124][125], duty-cycle control [126,127], load identification [128], and hybrid control strategy [129,130]. These strategies can be classified as single-sided control and double-sided control.…”

“…By sampling the voltage and current of the compensation and transmitter coils, the accurate identification of the receiver's position is achieved, thereby suppressing the misalignment. The back-end DC/DC converter-based approach is proposed in [118]. However, extra weight/volume, cost, and power losses will be unavoidable for the additional DC/DC converter.…”

High-Order Compensation Topology Integration for High-Tolerant Wireless Power Transfer

Wireless power transfer (WPT) has been a promising way to transfer power wirelessly over certain distances through the mutual inductance (MI) of the magnetically coupled transmitter and receiver coils, providing significant benefits of convenience, safety, and feasibility to special occasions. The stable output and efficiency cannot be maintained due to the load variation and the inevitable misalignment between the magnetic couplers. High-order compensation topologies that are highly flexible in design due to more compensation elements are essential for the WPT to suppress the load variation and misalignment effects. However, due to core loss and thermal management, high-power-level and high-frequency inductor design have always been challenging for WPT systems. Space occupation and cost are other aspects to be considered for inductor design. Thus integrating these additional bulky inductors into the main coils has been a critical trial. As a result, the compensation topologies’ original input and output profiles will change or even disappear. This paper reviews the existing high-order compensation topologies and their integration principles and implementation for the WPT to obtain high misalignment tolerance. The design objectives and challenges of the integrated compensation topology in terms of misalignment tolerance capability are discussed. The relevant control systems to cope with coil misalignment and load variations are investigated. Challenges and future development of the high-tolerant WPT are discussed.
