Stability of a DC Link with Low Energy Storage through an Original Regenerative Synchronous Drive
Résumé
This paper puts forward an analytical and practical analysis of the global stability dedicated to a low rating LC filter on a DC link for a rapid cycling synchronous drive. The first part describes the regenerative AC/DC front stage through an original bidirectional and self-commutated rectifier. The second part deals with the modelling of the AC/DC front stage, the DC link and the output synchronous drive. The last part analyzes the DC link stability taking into account the analytical correlation between the LC rating, the synchronous drive parameters and finally the feed-back control parameters of the PWM feeding. This contribution offers to designer a possible solution for on-board / embedded applications where sizing reduction and safety are simultaneously required.
