A Matlab tool for analysis of switch-mode power supplies

This paper presents a Matlab tool that can quickly perform all the most common analyses of linear, periodically time-varying circuits, like switch-mode power supplies or switched amplifiers. The circuit to be analysed is described as a set of state models, and from these, operating point, steady-state analyses, and open-loop and closed-loop linearised AC analysis can be performed. Example results of a Buck converter are shown.
