Dynamical Behavior of V^2C Control Boost Converter

摘要

A discrete iterative map model of V2C control boost converter was established to study the dynamical behaviors of the converter. By using parameter space map and bifurcation diagram, the effects of circuit parameters on the bifurcation behaviors of V2C control and current-mode control boost converters were analyzed. The phase portraits and time-domain waveforms of the V2C control boost converter were obtained by Runge-Kutta algorithm through piecewise smooth switching model. The research results indicate that V2C control boost converters can evolve into periodic and chaotic behaviors, and show weaker nonlinear behaviors than current-mode control boost converters.
