Abstract

In this paper, we are interested in studying the stability of the two-cell DC/DC buck converter. First, this system is described by a discrete nonlinear model in the state space. Next, we design a dynamic time-delayed feedback controller to assure equal distribution of the potential difference between the cells and to achieve a reference current through the load. According to the controller parameters, two cases are treated in this paper. A stability analysis of the system is carried out for each case. These results are confirmed with numerical simulations.
