Basic Experiment on the Integration of Grid-Connected Photovoltaic and Dynamic Wireless Power Transfer

Dynamic Wireless Power Transfer (DWPT) technology is attracting attention as a charging method for Battery Electric Vehicles (BEVs). Among others, the combination of DWPT and renewable energy is believed to indirectly reduce CO2 emissions from running BEVs. There have been several studies combining PV and DWPT, but they have been limited to simulations and have not yet included experiments. In this paper, we propose for the first time to connect a number of MPPT-controlled PV panels to a grid-connected DC bus and combine them with DWPT. Simulations and experiments using MATLAB/Simulink show that the proposed system can execute DWPT with stable power and overall power conversion efficiency, demonstrating the feasibility and effectiveness of the proposed system.
