In this study, a robust current switching control of converters is proposed. It is proved that the controller is able to guarantee global current regulation, as well as the maximum voltage and current ripple, simultaneously. Such features make it ideal for implementing power‐management strategies and to be used along fuel cells. The control scheme is shown to be robust against model uncertainty and since it is based on the piece‐continuous model instead of average models, it is suitable for operation under a wide range of conditions. Moreover, its complexity does not increase with the number of cells. Experimental evidence of the advantages and features of the proposed control is presented in a two‐cell boost converter.
