Dynamic Analysis of the Switched-Inductor Buck-Boost Converter Based on the Memristor

The direct current (DC)–DC converter presents abundant nonlinear phenomena, such as periodic bifurcation and chaotic motion, under certain conditions. For a switched-inductor buck-boost (SIBB) with the memristive load, this paper constructs its state equation model two operating statuses, investigates dynamic characteristics, draws analyzes diagrams of inductive phase portraits, some parameter changing by MATLAB simulation based on equation. Then, applying minor perturbations to parameters, phenomenon suppression method is explored controlling peak in continuous mode (CCM) keep run normally. Finally, power (PSIM) verifies that waveforms portraits corresponding parameters are consistent those simulation.
