N2 - In in-motion wireless power transfer (WPT) application, large current overshoot comes into being if the power transmission starts suddenly. For the safety of the equipment, the transient property when the power transmission starts needs to be improved. However, few studies have proposed transient control using accurate circuit models. In this paper, precise envelope modeling of circuit considering the discontinuous current mode of diodes is introduced for transient control. Besides, its application to the voltage trajectory generation with offline calculation is also proposed. The experimental results demonstrate that the proposed method can track reference current trajectory and eliminate the overshoot.
