This paper reveals that the dynamics of a converter loaded with other converters downstream are markedly different from those of a standalone converter and conventional design techniques developed for converters with a resistive load could destabilize the control loop of converters combined with other converters. Based on comprehensive small-signal analyses, this paper presents the proper way of designing the control loop of converters driving other converters downstream. The analysis and design results are verified by both time- and frequency-domain simulations.
