  • Abstract
    Past investigation on nonlinear phenomena in DC-DC converters assume ideal and instantaneous action of switches, for which the sampled data models yield piecewise smooth but continuous maps. In this paper we show that the unavoidable delay in the switching logic results in discontinuity in the map, which drastically changes the bifurcation structures.
