| Abstract |
Guidelines for HF interactions reduction within Distributed Power Systems or cascaded converters are
developed in this paper. The aim of this study is not only to avoid the destabilization or functionality
disturbance of converters because of HF interactions between converters, but also to decrease, under
specific operating conditions, the EMI filters size used between converters. Firstly the problematic of
HF interactions between cascaded converters will be recalled. A model considering the HF
interactions in closed-loop system and showing the influence of the control-loop is reminded. Using
the proposed model, effects of the control loop are shown. Results of practical validation showing the
influence of control loop absence on converter characteristics under HF interactions are studied.
Guidelines are presented in order to limit the influence of HF interactions and to decrease filter size in
open and closed-loop. A practical application validates the demonstrated approach of the converter
filter size decrease. |
