Bifurcation and Chaos, Boost DC-DC Converter


This work describes the bifurcation behavior of a modular peak current-mode controlled (CMC) dc-dc boost converter from quasi-periodicity to period-doubling. The parallel-input/parallel-output converter consists of two identical boost circuits and operates in the continuous current conduction mode. A nonlinear mapping in closed form is derived and bifurcation diagrams are generated using MATLAB. Results are verified using the circuit analysis package PSPICE.
