Dynamics and control of dc-to-dc converters driving other converters downstream

This paper reveals that the dynamics of a converter loaded with other conve rters downstream are markedly different from those of a standalone converte r and conventional design techniques developed for converters with a resist ive load could destabilize the control loop of converters combined with oth er converters, Eased on comprehensive small-signal analyses, this paper pre sents the proper way of designing the control loop of converters driving ot her converters downstream, The analysis and design results are verified by both time- and frequency-domain simulations.
