Dynamical analysis and circuit implementation of a DC/DC single-stage boost converter with memristance load

The DC/DC boost converter can exhibit nonlinear phenomena like chaos and periodic motion, which are influenced by system parameters, topological structure, load and pulse period. In this paper, we mainly investigate these phenomena in a DC/DC single-stage current-mode-controlled boost converter. This study focuses on the nonlinear dynamics when the load is memristance. Two independent nonlinear models are derived when the switch S is closed and open, respectively, and the bifurcation behaviors of the boost converter are investigated. By adjusting the bifurcation parameters, i.e., the pulse period T, chaos and periodic motion occur. Finally, an experimental circuit is presented to implement the DC/DC boost converter system with a memristance load, and the experimental results agreed well with the numerical results.
