In this paper, the nonlinear phenomenon in DC/DC buck converter is studied. A practical design for a DC/DC buck converter was considered in this study, which results in a more comprehensive understanding for the phenomenon. The nonlinearity of the buck converter is studied using the iteration mapping technique. The results showed that if the system has a well–designed buck converter as well as a feedback controller, then it does not exhibit any nonlinear behaviour. To verify these results, a buck converter, with non–practical parameters, was also studied. In this case, the results showed bifurcation and then chaotic behaviour for the output voltage and inductor current as the input voltage changes. A comparison between the two cases is discussed in more details.
