Analysis, simulation and experimental study of chaotic behaviour in parallel-connected DC–DC boost converters

The paper describes an experimental study of the bifurcation behaviour of a modular peak current-mode controlled DC–DC boost converter. The parallel-input/parallel-output converter comprises two identical boost circuits and operates in the continuous-current conduction mode. A comparison is made between the results obtained from an experimental converter with those obtained from bifurcation diagrams generated from previous work and waveforms from a new MATLAB/SIMULINK simulation presented in this paper. Another comparison is made between the modular converter diagrams with those of the single boost converter.
