Electric vehicles (EVs) have recently been significantly developed in terms of both performance and 10 drive range. There already are various models commercially available, and the number of EVs on road 11 increases rapidly. Although most existing EVs are charged by electric cables, companies like Tesla, 12 BMW and Nissan have started to develop wireless charged EVs that don't require bulky cables. 13 Rather than physical cable connection, the wireless (inductive) link effectively avoids sparking over 14 plugging/unplugging. Furthermore, wireless charging opens new possibilities for dynamic chargingcharging while driving. Once realised, EVs will no longer be limited by their electric drive range and the requirement for battery capacity will be greatly reduced. This has been prioritised and promoted worldwide, particularly in UK, Germany and Korea. This paper presents a thorough literature review on the wireless charging technology for EVs. The key technical components of wireless charging are summarised and compared, such as compensation topologies, coil design and communication. To enhance the charging power, an innovative approach towards the use of superconducting material in coil designs is investigated and their potential impact on wireless charging is discussed. In addition, health and safety concerns about wireless charging are addressed, as well as their relevant standards. Economically, the costs of a wide range of wireless charging systems has also been summarised and compared.

“…5, the relationship between the total impedance and the loop current of the series resonant circuit shows that the total impedance at the resonance point is 0.473, and the current value is at most 25.385, which is most beneficial for energy transmission. In addition, it can be seen that the frequency range which can be adjusted is small, and once it deviates from the resonance point, the impedance sharply increases, and the current suddenly drops [5].

Resonant Wireless Power Transfer (RWPT) is free from wired transmission. It has also realized long-distance power transmission, which has become one of the hotspots at home and abroad. Based on the existing research foundation, this paper focuses on the analysis of the inverter module, rectifier module and resonant coupling module from the components of RWPT. Further, PSpice simulation is used to analyze the IR2110 driving circuit and the transmission process of the whole system. Finally, a RWPT system is set up to explore the feasibility and effectiveness of theoretical analysis and practical experiments.

“…Simulations are carried out with free air as the medium. Most inductive chargers for biomedical implants incorporate planar circular or spiral coils [4,17,28,29] due to the space restrictions applying to the implantable coil. Optimal operation is achieved when the primary coil is perfectly aligned with the secondary coil.…”

Modern biomedical implantable devices provide an increasingly popular solution for health monitoring and medical issues. Their level of development in the coming years will depend on their reliability and endurance. Their powering and recharging capabilities are key factors for their dominance. In this work, series compensation topologies for use in inductive chargers of biomedical implantable devices are investigated with regard to their performance. The goal is to assess the possibility of reducing the component count of the implantable device and thus, increase its reliability and patient safety. Comparison is performed between the commonly used series-series compensation topology with a topology which incorporates no capacitors in the secondary side but only series compensation in the primary. Extensive investigation of the operation of the two topologies is made through mathematical analysis, simulations, and experimental evaluation, for the most popular schemes of operation, with regard to frequency selection. A prototype inductive charger, including a custom-made inductive link, was designed and built for the experimental evaluation of the system. Insights on the operation of both topologies are provided and the results show that primary-side series compensation can be a strong alternative to series-series compensation, in biomedical applications.
