Abstract
Every electric vehicle requires fast, safe, and reliable charging with optimal performance. Conventional plug-in charging systems have several issues that wireless charging eliminates. Wireless charging is also considered the most environmentally friendly and user-friendly option. It does not require bulky connectors and safety equipment that add cost and take up space. The majority of work focuses on presenting an overview and basic infrastructure of wireless power transfer systems. This paper describes the latest technological advancements in both far and near-field wireless charging methods. It then examines the near-field inductive charging method for both static and dynamic electric vehicle applications. The paper also discusses compensation networks' role in inductive power transfer systems, delving into the advancements made in compensation networks that enhance coil utilization and efficiency. Additionally, the paper presents various magnetic coupler designs and their optimization to improve overall magnetic coupling efficiency, pulsations, and power null region to support their suitability in static and dynamic applications. The paper also stresses the importance of safety when installing wireless power transfer systems, along roads or at home. As a result, updated standards from IEEE/SAE and IEC, analyzing system and equipment requirements, are suggested in this review. Based on the presented discussion, the DD with DDQ receiver coil is considered the most useful solution with LCC-S compensation, offering the highest electrical performance characteristics and a recorded efficiency of 93% for modern dynamic charging. Finally, double-sided DD coils with LCC-S compensation with voltage source output characteristics are recommended to reduce control complexity.
