Abstract

Cette invention concerne compensateur synchrone statique, comprenant au moins un pôle de convertisseur pour produire une première phase d'une forme d'onde de tension alternative ayant un cycle fondamental. La première phase de la forme d'onde de tension alternative comprend des régions alternées de charge et de décharge de pôle de convertisseur dans chaque cycle fondamental. Le(s) pôles de convertisseur comprennent une pluralité de cellules en pont en H en cascade, dont chacune comprend une source de tension continue et une pluralité de commutateurs. Les commutateurs peuvent être commutés de sorte à produire une pluralité d'états de commutation. Un dispositif de commande est configuré pour commander les états de commutation de la pluralité de commutateurs de chacune des cellules en pont en H en cascade sur la base des tensions de sources de tension en courant continu des cellules en pont en H et si la forme d'onde en CA est dans la région de charge de pôle de convertisseur ou la région de décharge de pôle de convertisseur.
