Abstract:
The purpose of this work is to design a multipurpose power electronic converter (PEC) that makes use of dual power sources, namely the grid and solar photovoltaic (PV) systems, in order to facilitate the charging process of plug-in electric vehicles (PEVs).
All modes of vehicles, including charging, propulsion (PP), and regenerative braking (RB), were successfully done by the design that was devised. The battery is either charged by the grid when the vehicle is in a stationary situation, or it is charged concurrently by both the grid and the solar photovoltaic system.
RB function, which makes use of the kinetic energy of the vehicle’s wheels, can also be used to charge the battery while the vehicle is operating in running mode. When operating in plug-in charging (PIC) mode, the proposed converter functions as an isolated SEPIC. However, when operating in solar PV charging mode, it functions as a non-isolated SEPIC.
Additionally, the suggested PEC can operate as a standard boost converter and a conventional buck converter, respectively, when operating in the PP and RB modes during operation. A presentation has been made that includes both the simulation and experimental validations for each and every mode of the proposed converter.
