Spectral decomposition based approach for DC-DC converters modeling

The modeling process presents a key step on the analysis and the control of DC-DC converters that can exhibit complicated nonlinear phenomena. In order to describe accurately the converter behavior, a discrete modeling technique is proposed; it allows the exact description of the system with a minimum of simplifying assumptions and validity hypothesis of the mode. The validation of the proposed method is achieved through simulation and comparative study results using some criteria such as the approximation error, computing time and allocated memory for data processing and storage.
