A new topology for bidirectional multi-input multi-output buck direct current-direct current converter

In this paper, a new topology for bidirectional multi-input multi-output buck direct current-direct current converter is proposed. For the proposed converter, the number of inputs and outputs is arbitrary and independent from each other. Moreover, the number of components of the proposed structure is less than the conventional type of the bidirectional multi-input multi-output buck direct current-direct current converter. The proposed converter can be used in applications that require separate voltage levels with bidirectional current path. The possibility of using different energy sources with different voltage-current characteristics, lower cost, continuous input current, and transformerless output are the major advantages of the converter. In this paper, the different operating modes of the proposed converter are explained. The performance and correctness operation of the proposed converter are validated by the simulation and experimental results.
