Abstract
Bidirectional wireless power transfer technology can realize the non-contact bidirectional flow of electric energy between devices. Compared with unidirectional wireless charging and wired charging, it is more intelligent, flexible and interactive. In high-power applications such as electric vehicle charging, bilateral LCC resonant networks are usually used. In this paper, a bidirectional wireless power transfer model of bilateral LCC with asymmetric parameters is established, and the power and efficiency characteristics of the system are analyzed in depth, and the approximate process and error analysis of the maximum efficiency point are given. Then the influence of parameter asymmetry on the system is also studied. The results show that the transferred power of the system is mainly affected by the resonant inductance, while the maximum efficiency is mainly affected by the parasitic resistance of the coil. Finally, the accuracy of the model is verified on a 1-kW prototype.
