Abstract: The ever-increasing demand for renewable energy resources as compared to conventional means of energy generation has resulted in a growing demand for more efficient power storage systems and applications. However, this necessitates the use of different converters that must be employed to achieve efficient voltage conversions right from the generation stage to the point power is stored in the battery banks. To achieve efficient conversions of the voltage levels, Bidirectional DC-DC Dual-Active-Bridge (DAB) converters can be employed. Accordingly, this research work involves use of a closed-loop PI controller for controlling the outputs of a DC-DC converter and compensating for the load disturbances. The Simulink-derived results indicate the input & output characteristics of the converter to achieve the design of a controller that is capable of providing significant tracking reference command without undergoing steady-state error, thereby offering a fast transient response. Hence, by maximizing the performance of the converter, the controller resolves the issues identified in the output current. The system was also implemented on a 400W laboratory experimental model with a view to additionally validate its performance effectiveness. As a whole, a DAB system was successfully designed, simulated, implemented and analyzed for employing in various energy storage applications
