Feasibility of Geometric Digital Controls and Augmentation for Ultrafast Dc-Dc Converter Response
A set of augmentation-based controls is introduced for DC-DC converters. The controls support null response to disturbances in line or load for basic DC-DC converters. Augmentation resembles lossy snubbers, and takes the form of switched resistance to dissipate extra stored energy, resistive paths to deliver energy to the load while energy storage is increasing, and switched capacitance from an augmented phase to maintain the load during a transient. Cases are given for line step increases and decreases, and step load increases and decreases for buck and boost converters. It is shown that designs based on straightforward energy computations yield performance that remains within the specified output ripple band even during extreme transients
