Bidirectional DISO DC-DC Converter Based on Lyapunov Control Strategy

This paper introduces a novel bidirectional dualinput single-output (BDISO) DC-DC converter to integrate an energy source and a battery to supply the desired load. The proposed BDISO converter can deliver power from input energy sources to the load simultaneously. Also, the proposed topology benefits from performing in buck, boost, Buck-boost, and bidirectional operating modes. Accordingly, Mathematical model of the proposed converter are described and analyzed as well. Furthermore, to obtain the closed-loop control of the suggested BDISO converter, the Lyapunov control strategy is applied, ensuring global stability and the advantage of fast dynamic response. Finally, the performance of the proposed converter is verified through experimental results obtained from manufacturing a prototype model of the BDISO converter.
