DC-DC Converters Modelling Approach Using Spectral Decomposition Theorem

DC–DC converters are nonlinear systems that exhibit a complicated nonlinear phenomena, its modelling presents the basic step of its analysis and control. In this work, we propose a discrete modelling technique that allows an accurate description of the converter behaviour with a minimum of simplifying assumptions and validity hypothesis. The proposed method validation is achieved by means of simulation and a comparative study results.
