N2 - The demand for the rapid wireless charging and high-power wireless charging is increasing. In order to improve the power transfer capacity, multiple inverters are usually connected in parallel to excite the different transmitting coils. respectively. The double-sided LCC compensation is the commonly used topology in practice application. However, the compensated coils and main coils in the resonant networks occupy much space, which is not allowed especially on the secondary side. In this paper, A method is proposed to integrate the compensated coils and main coils on the same side of the wireless power transfer (WPT) system consisting of two inverters connected in parallel, two resonant networks, and two rectifiers. All the four coils on the same side are integrated together and decoupled. Finally, the simulation model and experimental topology are built to verify the validity of the proposed method. The experiment results are consistent with the theoretical analysis. And the peak efficiency of the WPT system achieves 91.01%.
