Résumé :	The aim of this paper is to give a solution to unbatance problem of the input DC voltages of nine-level NPC-VSI used in high voltage and great power applications [1]. For that, one two-level PWM current rectifier-nine-level NPC VSI-PMSM cascade is presented. In the first part, we develop a knowledge model of nine-level NPC VSI and offers a space vector modulation of this converter . In the first case the input DC voltages of the multilevel inverter are assumed constant and equals, After that, we propose to study a new high voltage cascade two-level PWM current rectifier-nine-level NPC VSI-PMSM. This study shows particularly the problem of the stability of the DC voltages of the inverterl. Then, we propose a solution to the problem by employee closed loop regulation using classic PI regulator mode, We add 2 Clamping bridge to stabilize the eight DC input voltages of nine-level NPC VSI.
