| Abstract: | The dynamic wireless charging system can significantly reduce the weight and size of electric vehicle(EV)power batteries. Hence it has broad application prospects. A state-space model of dynamic wireless EV charging system is developed first based on the segmented multi-track scheme. Also, a system small-signal model is obtained to describe the dynamic characteristics. Then, with the help of an experimental platform and the actual values of system variables, dynamic changes in system output power and efficiency are analyzed in the dynamic charging process. Furthermore, the transient characteristics in the track switch-on process are investigated, as is the influence of switching position. Meanwhile, experiments are conducted to verify the proposed model and analysis conclusions.
