The operation parameter of the buck–boost converter is examined for its boundary of the first flip bifurcation. It is found that the parameters exhibit a linear relation for the same parameter at another bifurcation point. The bifurcation parameters also have a linear correlation between them. Theoretical analysis is presented to explain how this can occur. Simulation and experimental results at 20 kHz are used to present these novel results. Copyright © 2005 John Wiley & Sons, Ltd.
