摘要: Quasi-steady-state (QSS) large-signal models are often taken for granted in the analysis and design of DC–DC switching converters, particularly varying operating conditions. In this study, premise QSS is justified quantitatively first time. Based on QSS, converter under conditions reduced to linear time systems model. Thereafter, concept applied frequency-domain properties converters by using three-dimensional Bode plots, which then utilised optimisation controller parameters wide variations input voltage load resistance. An experimental prototype an average-current-mode-controlled boost built verify both time-domain measurements.
