“…In order to achieve this goal, the driving frequency and resonant frequency must all coincide with the frequency where the quality factor of the coil is maximized, and he further pointed out that the maximum quality factor will be achieved when the ratio between the radius of the coil and the cross-sectional radius of the conductor is roughly 9.5. Hasanzadeh et al [71] proposed a design algorithm to determine the optimal resonant frequency and relevant transfer efficiency for system architecture with two coils, and a trade-off between low resonant frequency and high transfer efficiency should be decided first. In [72,73], the operating frequency increased endlessly until the transfer power was just lower than the rated power with the purpose of improving transfer efficiency, which was actually the tradeoff between transfer efficiency and transfer power.…”

Strongly coupled magnetic resonance (SCMR), proposed by researchers at MIT in 2007, attracted the world's attention by virtue of its mid-range, non-radiative and high-efficiency power transfer. In this paper, current developments and research progress in the SCMR area are presented. Advantages of SCMR are analyzed by comparing it with the other wireless power transfer (WPT) technologies, and different analytic principles of SCMR are elaborated in depth and further compared. The hot research spots, including system architectures, frequency splitting phenomena, impedance matching and optimization designs are classified and elaborated. Finally, current research directions and development trends of SCMR are discussed.

a b s t r a c tThe deficiency in the availability of petroleum products has given rise to the incorporation of electric vehicles (EVs) globally as a substitute for the conventional transportation system. Significant research has been pursued over last two decades in the development of efficient EV charging methods. A preliminary review of few methods developed for wireless charging revealed that ICPT is a promising and convenient method for the wireless charging of EVs. This paper includes the equivalent circuit analysis and characteristics of the ICPT system and focuses on the research progress in respect of the designs for the charging coil, leakage inductance compensation topologies, power level enhancement and misalignment toleration. The improvement in these factors has been essential for the implementation of EV charging. A brief discussion over design process and control of ICPT system has been added. Conclusions have been made on the basis of the information extracted from the literature and some future recommendations are provided.

Abstract. The Inductive power transfer (IPT) systems' efficiency is determined by kinds of parameters. Aim at maximum the power transfer efficiency for Inductive power transfer (IPT) system, the efficiency of four basic topology IPT systems is analyzed. Based on the analysis, genetic algorithms (GA) are used to optimize IPT systems parameters to achieve the maximum of the power transfer efficiency. Before the GA optimization process, the IPT systems are compensated in a resonance condition which can achieve to minimize VA rating of the power supply and maximum power transfer. In the process of GA optimization, to ensure the final solutions achieving bifurcation-free operation, the solutions that generate bifurcation phenomenon (multi zero phase angle frequency) are excluded. The simulation results verify that the GA can find the best optimal solutions for all topology IPT systems.
