Pulse Density Modulation Controlled WPT Charger for LEVs

Light Electric Vehicles (LEV) are increasingly used today to provide mobility in crowded cities. The charging process of LEVs has been one of the issues that should be paid attention to. For this purpose, LEVs owned or rented by users need to be charged quickly and reliably. By using Wireless Power Transfer (WPT), this needed quick and reliable charging can be achieved for LEVs. In this paper, Pulse Density Modulation (PDM) is used for charging in Constant Voltage (CV) mode during wireless charging of LEVs with WPT. The simulation study required for CV charging was carried out with MATLAB/Simulink. A WPT system has been proposed that produces a constant output voltage in response to changing equivalent load resistance in CV charging mode.
