Abstract :
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. The effects of tolerances on the values of the energy storage inductors for the two converters are investigated. 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.
