This paper presents a distributed switching control framework for parallel DC‐DC buck converters. The problems of voltage regulation and current sharing, as the technical challenges in DC networks, are studied from the switching dynamical systems and multi‐agent systems points of view. The problem is described as an interconnected switched affine system where the diffusive coupling of current errors between converters and converters' voltages are considered system variables. Then, by designing distributed min‐projection switching techniques, switching control signals are generated to achieve voltage regulation and current sharing control objectives. The stability analysis proceeds based on the relay control concept to guarantee the asymptotic stability of the error signals. Finally, the performance and effectiveness of the proposed control strategy are demonstrated by numerical simulations and experimentally on a small‐scale network of converters, and the results are investigated.
