Traditional Wireless Power Transfer (WPT) systems only have one energy transmission path, which can hardly meet the power demand for high power applications, e.g., railway applications (electric trains and trams, etc.) due to the capacity constraints of power electronic devices. A novel WPT system based on dual transmitters and dual receivers is proposed in this paper to upgrade the power capacity of the WPT system. The reliability and availability of the proposed WPT system can be dramatically improved due to the four energy transmission paths. A three-dimensional finite element analysis (FEA) tool ANSYS MAXWELL (ANSYS, Canonsburg, PA, USA) is adopted to investigate the proposed magnetic coupling structure. Besides, the effects of the crossing coupling mutual inductances among the transmitters and receivers are analyzed. It shows that the same-side cross couplings will decrease the efficiency and transmitted power. Decoupling transformers are employed to mitigate the effects of the same-side cross couplings. Meanwhile, the output voltage in the secondary side can be regulated at its designed value with a fast response performance, and the system can continue work even with a faulty inverter. Finally, a scale-down experimental setup is provided to verify the proposed approach. The experimental results indicate that the proposed method could improve the transmitted power capacity, overall efficiency and reliability, simultaneously. The proposed WPT structure is a potential alternative for high power applications.

This paper analyzes two different transportation electrification charging schemes, i.e., an embedded wireless power transfer system and an overhead catenary wire system, for use in range extension of electric vehicles on rural highways. The efficiency, feasibility, and benefits of the two schemes are examined. Electric vehicles currently lack widespread popularity mainly due to battery limitations, especially for long distance travel. The rural highway charging methods presented here can greatly increase the range of electric vehicles while decreasing battery sizes. Average modeling approaches for power electronics and vehicle usage were developed in MATLAB/Simulink to compare the two systems, each at two power levels. 30 kW and 48 kW were chosen to demonstrate the differences between power levels, both capable of maintaining a positive net charge on a dynamic electric vehicle.Component efficiencies, energy transfer levels, and installation percentages for the various models were determined. The models were applied to California highway I-5 to show immense potential savings over gasoline vehicles. It was shown that catenary charging is cheaper and has higher energy transfer than wireless; however, it has difficulty servicing all vehicle types, has visible wires, and requires more maintenance. A small scale hardware prototype of the WPT system was created in order to demonstrate the feasibility of power transfer at the proposed relative distances and speeds.
