  • Overloading the DC converter, in particular a DC converter module can damage the corresponding DC converter module.
  • It is therefore an idea of the present invention to take this knowledge into account and to limit the maximum output current of the individual DC / DC converter modules in a DC / DC converter with several DC / DC converter modules. In this way, even with a high power requirement on the output side of the DC voltage converter, the power output of the DC voltage converter, in particular each individual DC voltage converter module of a DC voltage converter with several parallel connected DC voltage converter modules, can be limited to a permissible level.

If the DC / DC converter with the multiple DC / DC converter modules were to provide the necessary control variable for reaching the output voltage at the beginning of the charging process of a capacitor, a very high charging current would be set for the capacitor at the beginning of this charging process. This high charging current could overload one or more of the DC / DC converter modules. Therefore, through a suitable initialization of the respective current regulator for the individual DC / DC converter modules, the control variable for the pilot control device is superimposed in order to limit the maximum output current of the individual DC / DC converter modules to a maximum current value.

Abstract

La présente invention concerne une commande d'un convertisseur continu/continu (10) comprenant une pluralité de modules convertisseurs continu/continu (4-1, 4-2). A cet effet, une grandeur de commande centrale est générée pour tous les modules convertisseurs continu/continu pour une commande régulée en tension du convertisseur continu/continu. De plus, une variable de commande basée sur le courant peut être générée additionnellement pour chaque module convertisseur continu/continu. La puissance de sortie, en particulier le courant de sortie de chaque module convertisseur continu/continu, peut être ajustée individuellement par combinaison de la variable de commande basée sur la tension et de la variable de commande basée sur le courant. Il est ainsi possible d'éviter une surcharge des modules convertisseurs continu/continu.
