The precise discrete mapping of the voltage fed boost converter which is operated under the discontinuous mode(DCM)is proposed.Based on the mapping,the relationship between the voltage fed coefficient K and the bifurcation occurred in the converter was analyzed. Therefore,the range of the voltage fed coefficient K for the stability operation of the boost converter is given exactly.Bifurcation and chaos in the voltage fed boost converter is studied by simulation and experiment further.It will provide a reference method for modeling and analyzing bifurcation and chaos of general dc/dc converter.
