“…Therefore, the total magnetic field intensity can be enhanced by using dual transmitters due to the overlapped magnetic coupling structure. Furthermore, in order to enhance the coupling mutual inductances between the transmitters and the receivers, all the transmitters and receivers are wound around U-type ferrite cores as [14] did. It is worth noticing that the ferrite cores can be any other types e.g., E-type, and/or I-type for various applications.…”

“…However, the power capacity of a traditional WPT system is limited by the constraints of semiconductor devices. Besides, the single transmitter and single receiver based magnetic coupling structure results in a low reliability of the WPT system due to the only one energy transmission path, and it unlikely meets the requirement of high power applications since public transport systems need to be rated at hundreds of kVA or more (up to MW scale) [14]. Therefore, it is significant to investigate approaches which can enhance the transmitted power of WPT systems by using low-power and low-cost semiconductor devices for high power application e.g., railway transport (electric trains and trams, etc.)…”

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.

The single resonant inverter is widely employed in typical inductive power transfer (IPT) systems to generate a high-frequency current in the primary side. However, the power capacity of a single resonant inverter is limited by the constraints of power electronic devices and the relevant cost. Consequently, IPT systems fail to meet high-power application requirements, such as those in rail applications. Total harmonic distortion (THD) may also violate the standard electromagnetic interference requirements with phase shift control under light load conditions. A power regulation approach with selective harmonic elimination is proposed on the basis of a parallel multi-inverter to upgrade the power levels of IPT systems and suppress THD under light load conditions by changing the output voltage pulse width and phase shift angle among parallel multi-inverters. The validity of the proposed control approach is verified by using a 1,412.3 W prototype system, which achieves a maximum transfer efficiency of 90.602%. Output power levels can be dramatically improved with the same semiconductor capacity, and distortion can be effectively suppressed under various load conditions.
