Annotation: The problem in question is constructing a buck voltage converter with minimum possible duration of transient processes that can be achieved at a given fixed frequency of conversion. The goal is attained by controlling both fronts, as well as through adaptive adjustment of feedback coefficients. It is demonstrated that when converters process small perturbations, duration of the transition process can be reduced to a minimum of one cycle (a conversion period).
