Abstract

AbstractThe voltage regulation and power sharing for parallel direct current–direct current (DC–DC) buck converters is studied in this paper by using the multi‐agent consensus theory. At the first step, the control problem of parallel DC–DC buck converters is modeled as the consensus problem of multi‐agent system. Different from the most existing algorithms for parallel DC–DC buck converters, a new distributed cooperative control algorithm is proposed to implement plug‐and‐play and to enhance the system's flexibility. For the current‐loop, a finite‐time control algorithm is employed to improve the dynamic response for the current tracking. The rigors stability analysis is given and the simulation result is presented.
