Power Integrations<\/a>\u00a0a pr\u00e9sent\u00e9 la\u00a0famille SCALE-iFlex LT NTC de\u00a0<\/a>circuits d’attaque de grille de module IGBT\/SiC<\/h2>\n

Les nouveaux drivers de grille ciblent le nouveau style populaire de modules IGBT doubles de 100 mm x 140 mm, tels que le Mitsubishi LV100 et l’Infineon XHP 2, ainsi que leurs variantes en carbure de silicium (SiC) jusqu’\u00e0 une tension de blocage de 2300 V. Les drivers SCALE-iFlex LT NTC fournissent des donn\u00e9es NTC (Negative Temperature Coefficient (NTC) \u2013 une mesure de temp\u00e9rature isol\u00e9e du module de puissance \u2013 qui permettent une gestion thermique pr\u00e9cise des syst\u00e8mes de convertisseurs. Ceci est particuli\u00e8rement important pour les syst\u00e8mes avec plusieurs modules mis en r\u00e9seau en parall\u00e8le, assurant un partage de courant correct et am\u00e9liorant consid\u00e9rablement la fiabilit\u00e9 globale du syst\u00e8me.
\nThorsten Schmidt, responsable du marketing produit chez Power Integrations, a comment\u00e9 : \u00ab Les concepteurs de syst\u00e8mes ferroviaires et d’\u00e9nergie renouvelable utilisant des conducteurs SCALE-iFlex b\u00e9n\u00e9ficient d\u00e9j\u00e0 de performances syst\u00e8me accrues ; l’approche SCALE-iFlex g\u00e8re la mise en parall\u00e8le de mani\u00e8re si experte qu’un module sur cinq peut \u00eatre \u00e9limin\u00e9 sans perte de performance ni d\u00e9classement actuel. L’ajout d’une sortie NTC isol\u00e9e r\u00e9duit la complexit\u00e9 mat\u00e9rielle (en particulier les c\u00e2bles et les connecteurs) et contribue \u00e0 l’observabilit\u00e9 du syst\u00e8me et aux performances globales.<\/p>\n

Un excellent partage du courant<\/h3>\n

Bas\u00e9s sur la technologie \u00e9prouv\u00e9e SCALE-2<\/a>\u00a0de Power Integrations, les circuits d’attaque de grille SCALE-iFlex LT am\u00e9liorent la pr\u00e9cision du partage du courant et augmentent ainsi la capacit\u00e9 de transport de courant des modules \u00e0 plusieurs parall\u00e8les de 20 %, permettant aux utilisateurs d’augmenter consid\u00e9rablement l’utilisation des semi-conducteurs de leurs piles de convertisseurs. Cela est possible parce que le contr\u00f4le localis\u00e9 de chaque unit\u00e9 MAG (Module Adapted Gate driver) 2SMLT0220D assure un contr\u00f4le et une commutation pr\u00e9cis, permettant un excellent partage du courant. Le serrage actif avanc\u00e9 (AAC) est utilis\u00e9 pour fournir une protection pr\u00e9cise contre les surtensions.
\nPour augmenter encore l’encombrement, jusqu’\u00e0 quatre modules d’alimentation pilot\u00e9s par MAG peuvent \u00eatre connect\u00e9s en parall\u00e8le \u00e0 partir d’une seule unit\u00e9 IMC (Isolated Master Control) 2SILT1200T, qui peut \u00e9galement \u00eatre mont\u00e9e sur un module d’alimentation gr\u00e2ce \u00e0 son contour compact. Les pilotes de grille sont enti\u00e8rement qualifi\u00e9s selon les sp\u00e9cifications IEC 61000-4-x (EMI), IEC-60068-2-x (environnement) et IEC-60068-2-x (m\u00e9canique), et subissent des tests de type complets – basse tension, haute tension, cyclage thermique – raccourcissant le temps de d\u00e9veloppement du concepteur de 12 \u00e0 18 mois. Un ensemble complet de fonctions de protection est inclus, et les pi\u00e8ces sont disponibles en option avec un vernis de protection.<\/p>\n
