Performance Analysis of Dual Active Full Bridge Converter with V2G and G2V Operating Modes in EV Application

Abstract

The study's primary purpose is to produce a modern method for Electric Vehicles (EVs) that manages the amount of electricity that enters and exits the batteries in line with a predetermined standard. Two different modes of operation are available for electric vehicles: Secondly, in the discharge state, which is referred to as Voltage-to-Ground (V2G), 1) in the charging mode, also referred to as the G2V mode. You can adjust the charging voltage during charging mode thanks to voltage-oriented control. On the other hand, the discharging mode employs current-oriented control to regulate the amount of battery discharge current linked to the grid. The grid connection provided by PVA makes switching between electricity from renewable sources easier. To analyze the proposed DAFB topology, various operating situations and reference set points for the discharge and charge currents of the batteries are used. Each step of the design and modeling process is carried out with the assistance of MATLAB software, which produces graphical outputs associated with time intervals.
