A Novel Multi-Objective Topology for In-Motion WPT Systems with an Input DG Source

On-road dynamic charging of electric vehicles with distributed generation (DG) sources has emerged recently as a cost-saving means for modern transportation. The resonant converter as a common WPT topology is not a suitable choice here due to several deficiencies. In this paper, a novel low-frequency multi-objective WPT topology, based on loosely coupled flyback converter with the compatible energy recovery circuit is proposed against the restriction of resonant converter. In this system, an input DG source (photovoltaic (PV)) produces its maximum possible power to supply the EV according to the MPPT algorithm. The remaining energy is stored in the back-up battery during each switching interval and can be injected to the EV drive train, whenever the PV power is not in access. Extensive simulation results using MATLAB-Simulink is presented to validate the proposed WPT topology and its multi-stage control system.
