Abstract

This paper investigates nonlinear bifurcation behaviors in the input-series output-parallel (ISOP) connected DC–DC converters under peak current control operating in continuous conduction mode. Circuit simulation demonstrates typical nonlinear phenomena occurring in the ISOP connected DC–DC converters. A precise discrete-time mapping model is presented to analyze the stability and bifurcation phenomena in the ISOP connected DC–DC converters. Interaction of the outside voltage loop and inner loop leads to coexisting slow-scale and fast-scale bifurcation which is investigated under two different values of the bandwidth.
