Abstract :
This paper presents the most recent progresses in deep researches to the large-signal modeling technique for current-mode-controlled SMPS modules distributed in an interconnected dc power system. Small-signal analysis to the lower- frequency power transfer model for Cuk power stage is carried out and both the time-domain and s-domain small-signal models are presented. Relations between the large-signal models respectively for current-mode-controlled and voltage-mode- controlled power stages are also clarified in this paper.
