Multi-port bidirectional converter facilitates bidirectional power flow control, with high power density, and superior efficiency. The application of these converters is in interfacing renewable energy sources (RES) like wind, solar, mini or micro hydro etc, energy storage systems (ESSs), Fuel cells (FCs), etc. with microgrids, utility grids, and EV charging infrastructure. In this work, a triple active bridge (TAB) DCIDC converter is employed as a three-port isolated bidirectional DCIDC converter for off-grid EV charging applications by connecting solar PV and BESS for EV battery charging. The solar PV power is extracted at MPP and is utilized to charge the EV battery and to charge/discharge the BESS. Here, the BESS acts as the power buffer. The single-phase shift modulation is used for power flow control and constant current charging of EV battery by adjusting phase shift appropriately. The performance of the converter is studied in MATLAB-based simulation and the findings from the simulation are thoroughly elucidated and discussed.
