Abstract
(EN)
A power converter (2) comprises an arm (5) in which a plurality of converter cells (7), each including two or more switching elements (31p, 31n), a power storage element (32), and a pair of output terminals (P1, P2), are connected in series. A control device (3) controls the voltages of the plurality of converter cells (7) by phase-shift PWM control using carrier signals for the respective converter cells (7). Each of the converter cells (7) includes a switch (34) for bypassing the converter cell (7). When detecting a malfunction of the converter cell (7) in the arm, the control device (3) allows bypassing of the malfunctioning converter cell in the arm and improves unevenness, caused by the malfunction of the converter cell (7), in phase intervals of carrier signals for a plurality of normally operating converter cells in the arm.

Convertisseur de puissance (2) comprenant un bras (5) dans lequel une pluralité de cellules (7) de convertisseur, comprenant chacune deux éléments de commutation ou plus (31p, 31n), un élément de stockage d'énergie (32), et une paire de bornes de sortie (P1. P2), sont connectées en série. Un dispositif de commande (3) commande les tensions de la pluralité de cellules (7) de convertisseur par commande PWM à déphasage à l'aide de signaux de porteuse pour les cellules (7) de convertisseur respectives. Chacune des cellules (7) de convertisseur comprend un commutateur (34) pour contourner la cellule (7) de convertisseur. Lors de la détection d'un dysfonctionnement de la cellule (7) de convertisseur dans le bras, le dispositif de commande (3) permet de contourner la cellule de convertisseur qui dysfonctionne dans le bras et améliore l'irrégularité, provoquée par le dysfonctionnement de la cellule (7) de convertisseur, dans des intervalles de phase de signaux de porteuse pour une pluralité de cellules de convertisseur fonctionnant normalement dans le bras.
