In this paper, a 25-kW Wireless Power Transfer (WPT) system is considered for in-motion charging of an electric bus. The goal of this research is to derive a control strategy for the primary side of a wireless Electric Vehicle (EV) charger, with the objective to achieve fast dynamics and full control over the primary coil current and the amount of transferred power. To this aim, a dual-loop controller...
Traditional in-motion (dynamic) wireless power transfer (WPT) is based on elongated power transmitting tracks. It suffers from low efficiency, having complex and not fully utilized magnetic structures, among other drawbacks. In the case of lumped transmitter coils commeasurable in size with the receiver coil, which has been recently proposed for the in-motion WPT, the power transfer is intermittent...
