Abstract: A switching dc-dc converter in closed-loop steady-state constitutes an operating point in the space of parameters describing its model. The inadequacy of conventional design of regulated converters, which is based on the assumption of small-signal perturbations about a single operating point, is addressed. A systematic and general modelling based on a grid-point approach is thus proposed. Under this modelling approach, multiple operating points within the parameter space are reduced to some defined grid-points describing the complete operation space of a regulated converter subjected to large-signal disturbances. The operation subspace of a given grid-point is analyzed. An example based on a PWM-type boost converter is to be given.
