EV Battery Charging Using Bi-Directional Converter With Buck Mode

Bi-directional converters are essential in Vehicle-to Grid (V2G) applications. This converter plays a critical role in charging the battery by transferring energy from the grid to the Electric vehicle as well as discharging the battery by transferring energy from the electric vehicle to the grid when demand is high. The operation of a DC-DC bidirectional converter that charges the battery of an electric vehicle while in buck mode is examined in this paper. The bidirectional converter is under the control of a closed-loop PI control circuit. The MATLAB/Simulink environment is used to simulate the proposed bidirectional converter and the control circuit. A Proteus SPICE model is also utilised to simulate the gate drive circuit for the MOSFET switches used in the converter. The paper also presents various simulation results obtained. These results suggest that this converter can be used in multiple applications, including Vehicle-to-Grid (V2G) applications.
