Abstract
This work deals with the development of a multifunctional power electronic converter (PEC) utilizing dual power sources (grid and solar photovoltaic (PV)) for charging phenomenon of plug-in electric vehicles (PEVs). The developed configuration accomplished all modes of vehicles (charging, propulsion (PP) and regenerative braking (RB)). In standstill condition of vehicle, the battery is either charged by grid or simultaneously by both grid and solar PV system. In running mode, the battery can also be charged through RB operation by utilizing kinetic energy of vehicle wheels. The proposed converter operates as an isolated SEPIC in plug-in charging (PIC) mode and as a non-isolated SEPIC in solar PV charging mode. Further, in PP and RB modes, operation of the proposed PEC as a conventional boost converter and conventional buck converter, respectively. Both the simulation and experimental validations for all modes of the proposed converter have been presented.
