Title
(EN) SYSTEM FOR PRECHARGING A DC LINK IN A VARIABLE SPEED DRIVE
(FR) SYSTEME SERVANT A PRECHARGER UNE LIGNE DE COURANT CONTINU DANS UNE COMMANDE A VITESSE VARIABLE
Abstract
(EN)
A variable speed drive (104) with a converter (202) that is controllable to precharge a DC link (204) is provided. The variable speed drive (104) also includes an inverter (206). The converter (202) converts a fixed line frequency, fixed line voltage AC power from an AC power source (102) into DC power. The DC link (204) filters the DC power from the converter (202). Finally, the inverter (206) is connected in parallel with the DC link (204) and converts the DC power from the DC link (204) into a variable frequency, variable voltage AC power. The converter (202) includes a plurality of pairs of power switches, wherein each pair of power switches includes a reverse blocking power switch arrangement (454, 650A, 652B) connected in anti-parallel to another reverse blocking power switch arrangement (456, 652A, 650B). Alternatively, each pair of power switches includes a reverse blocking power switch (454) connected in anti-parallel with a silicon carbide controlled rectifier (500).

Commande à vitesse variable (104) comportant un convertisseur (202) pouvant être contrôlé afin de précharger une ligne de courant continu (204). Cette commande à vitesse variable (104) comprend également un convertisseur continu-alternatif (206). Le convertisseur alternatif-continu (202) convertit un courant alternatif de tension et de fréquence de ligne fixe provenant d'une source de courant alternatif (102) en courant continu. La ligne de courant continu (204) filtre le courant continu provenant du convertisseur alternatif-continu (202). Enfin, le convertisseur continu-alternatif (206) est couplé en parallèle à la ligne de courant continu (204) et convertit le courant continu de ladite ligne (204) en courant alternatif de tension et de fréquence variables. Le convertisseur (202) comprend une pluralité de paires de commutateurs de courant, chacune de ces paires comportant un système de commutation de courant à blocage inversé (454, 650A, 652B) couplé de façon anti-parallèle à un autre système analogue (456, 652A, 650B). Dans un autre mode de réalisation, chaque paire de commutateurs de courant comprend un commutateur de courant à blocage inversé (454) couplé anti-parallèle à un redresseur (500) contrôlé au carbure de silicium.
