The advances in the field of power electronics have created a superior platform for interfacing clean renewableresources with the ever-growing energy storage technology. In this paper, a multidirectional power flow operation in thethree-port isolated DC-DC converter (TBDC) topology has been demonstrated for interfacing different battery energystorage sections to increase the system reliability. Comparison of multiple battery integration with dual active bridge andTBDC has been presented. Converter analysis has been conducted using the Fourier series harmonic model and converterloss calculation is also presented. Power flow controller has been proposed for closed-loop control of the TBDC. Theperformance of the converter has been tested using MATLAB-based simulation and three modes of power flow controloperation have been verified through scaled down laboratory experimental setup.
