Abstract: An isolated voltage source fed modular dual-input DC/DC converter with battery storage system for telecom load application is proposed in this paper. The proposed system has two individual inputs with rectifiers that are connected in parallel at secondary circuit for achieving constant voltage across the load. The proposed system integrates two energy sources resulting in an advantage of having compact structure with less number of components. Complete design of the proposed converter with FPGA based digital control strategy have been presented in this paper. The proposed control scheme aids in achieving stable current sharing of load current. Simple structure, current sharing of load and self-load regulation makes the converter configuration innovative for synchronized power management in dual-input telecom load application. The simulation analysis of the proposed converter has been executed utilizing MATLAB Simulink environment. A laboratory prototype has been developed and tested for 1.1 kW power. Simulation and hardware results validates the robustness of the proposed system under variable load as well as input voltage variation. � 2018 IEEE.
