Analysis and stabilization of simple model DC / DC converter This paper studies a switched dynamical system based on a simple model DC / DC converters. First, we consider the single DC / DC converter with constant voltage input. In order to analyze system dynamics, we adopt a piecewise constant modeling, extract essential parameters in a dimensionless circuit equation. Applying the mapping. procedure, we have analyzed stability of fixed points. We have implemented a simple test and analyzed the phenomena. Second, we consider the parallel DC / DC converters with constant voltage input. The circuit dynamics is described by piecewise linear equation where internal resistance of inductor is not omitted. And to stabilize the unstable waveform that obtained in the result. We used the temporal control rule for stabilization. We have implemented a simple test and analyzed the phenomena. Third, we consider the DC / DC converter with a photo-voltaic input. Input of photo-voltaic was expressed by an equivalent circuit. And approximate equivalent circuit by current-controlled voltage source. We have implemented a simple test and analyzed the phenomena.
